That was not exactly a scientific method to evaluate Iran's economy it was something to prove Iran's position based on feelings compared to Brazil's economy.
Brazil :
Population
214 million (Iran 85 m)
GDP $
1.44 T (Iran $200 b Worldbank data)
Exports $
280 billion (Iran $180-200)
Foreign reserves $
327 billion (Iran $85-230 b)
Brazil is self efficient in food production and exporter of food.
Similar characteristic (almost same numbers)
* They put infrastructure under category of industry (same 17% in Iran)
Oil production 3 million barrel of Brazil vs 2.5 million barrel of Iran
Gas production of Brazil is almost at 1/8 of Iran's.
Differences :
Iran's Gini coefficient is 42 vs Brazil's 53
Iran
Unemployment and HDI is almost same.
Agriculture
FAO
It's strong section of Brazil (but numbers are not that much in favor of Brazil as it should be )
Agriculture Total @2020 Brazil $135 billion vs Iran $91 billion.
Brazil produces ~9.5 times more meat compared to Iran.
Brazil agriculture output:
worldbank view of Iran's agriculture $23 billion
As you may know Brazil shines in agriculture and they have 4.9 more land compared to Iran.
Brazil is ahead of Iran in livestock production and number of products.
Even with all their advantages, there are fields in agriculture that Iran is doing very well like :
vegetables, fruits and wheat production
Brazil had ~$223 billion agriculture and Iran had ~$99 B.(2020 data)
Industry
Steel
In steel industry, Brazilian crude steel production was 32.2 million tons in 2019.
According to the World Steel Association (WSA), Iran produced over 28 million metric tons of steel in 2021, putting it just behind Brazil.
Chemical
In 2011, Brazil had the 6th largest chemical industry in the world.Since then their installed capacity didn't change that much.
at year 2017 they had $120 billion revenues.(chemical and petrochemical industries 2.5% of brazil's GDP)
Iran's petrochemical industry currently has 90m tonnes/year of production capacity.
Paper
In the paper and cellulose sector, Brazilian pulp production was 19.691 million tons in 2019.
Reserved space for Iran's data.
Pharmaceutical
Brazil was considered the sixth largest pharmaceutical market in the world. Drug sales in pharmacies reached around R $57 billion (US $17.79 billion) in the country.
Total healthcare spending is expected to rise from $24.3 billion in 2008, to $96 billion by 2017, reflecting the increasing demand on medical services.[3] Total health spending was equivalent to 6% of GDP in Iran in 2017
Footwear
In the leather-footwear sector (Footwear industry), in 2019 Brazil produced 972 million pairs. Exports were around 10%, reaching almost 125 million pairs. Brazil is in the 4th position among the world producers, behind China (who produces more than 10 billion pairs), India and Vietnam, and in 11th place among the biggest exporters.
"An estimated 185 to 210 million pairs of footwear were produced in the country last year (March 2016-17)," Iran
Textile
In Textile industry, Brazil, despite being among the 5 largest producers in the world in 2013, and being representative in the consumption of textiles and clothing, has very little insertion in global trade.
Brazil's participation in the world trade in textiles and clothing is only 0.3%, due to the difficulty of competing in price with producers in India and mainly in China.
There are a lot of small companies related to textile industries in Iran which they had $100-200 million exports.
Electricity
Brazil, In Electronics industry, In 2019, about 3% of the national GDP. Exports were US $5.6 billion, and the country's imports were US $32.0 billion. Installed capacity (2021) 181,532 MW.
TEHRAN – Iran’s total installed electricity generation capacity has reached 83,350 megawatts (MW) @2020.
Appliances
In the household appliances industry, sales of so-called "white line" equipment (refrigerator, air conditioning and others) were 12.9 million units in 2017.Brazil
TEHRAN – Iran’s Acting Industry, Mining, and Trade Minister Hossein Modares Khiabani says the country’s home appliance manufacturers currently have the capacity to produce 20 million units every year, IRIB reported. @2020
Car
The most popular cars usually have small engines like 1.0 or 1.4 and are of flexible fuel using ethanol and gasoline.
All manufacturers on the list have assembling facilities in Brazil:
Fiat (22,56%)
Volkswagen (22,13%)

Kia (1,8%)
production 2.2 million cars per year@ 2020.
Based on the OICA data, Iranian automakers produced 894,298 vehicles in 2021 to register a two percent increase compared to 2020, IRNA reported.(quality is much lower compared to cars that made in Brazil).
Truck
In 2021, approximately 164.95 thousand trucks were produced in Brazil, a significant increase of more than 73 percent in comparison to the previous year.
Iran, capacity is at ~6000 but no report on actual production in recent years.

(if there is a mistake in data and numbers or you have better source close to year of 2020/2021 related to these sections , tell me)
Industry part 2
Travel (domestic)
Number of passengers carried by railways of Brazil improved by 1.02 % from 15,648.0 million passenger-km in 2016 to 15,807.0 million passenger-km in 2017.
Number of passengers carried by railways of Iran jumped by 14.84 % from 13,270.0 million passenger-km in 2017 to 15,239.0 million passenger-km in 2018.
Roads
Brazil
Roadways: total: 2 million km (2018)
paved: 246,000 km (2018)
unpaved: 1.754 million km (2018)
Iran has long paved road system linking most of its towns and all of its cities. In 2016 the country had 221,000 km (137,323) of roads , of which 73% were paved
Domestic air travel
The country’s domestic passengers notched up 0.7% year-on-year in the 8M ending Aug-2019, to 62 million. Traffic was up 0.1% as Brazil ’s domestic capacity fell by 2.2% year-on-year.
Iran - Air transport,21,641,450 passengers carried (before Covid)
Brazil - Embraer
Commercial aircraft deliveries 130 @2020
Iran
Commercial aircraft deliveries 0 @2020 (maybe few trainers/VIP aircraft)
Brazil 366 vehicles per 1000 people
Iran 175 vehicles per 1000 people
Tire
Brazil tire market is expected to grow from USD5.92 billion in 2020 to USD8.63 billion by 2026. (I could not find anything about production in Brazil)
The production of tire in Iran has reached to 38.475 million tires during the first 11 months of the current Iranian year (March 21, 2019-February 19, 2020).
Demand for tire in Brazil is higher.
Refinary
The crude oil refining capacity in Brazil amounted to 2.41 million barrels per day in 2020.
Iran’s refining capacity reaches 2.3m bpd. (oil)
Oil
In 2020, Brazil produced an average of 2.94 million barrels per day (b/d) of crude oil and condensate, an increase of more than 150,000 b/d on average compared with 2019.
In its Monthly Oil Market report in February, the OPEC put Iran's average production in 2021 at slightly over 2.4 million bpd, an increase from an average of 2 million bpd in 2020.
Natural Gas
Natural gas production in Brazil has more than doubled in one decade, reaching over 43.6 billion cubic meters in 2020.
In 2020, natural gas production in Iran amounted to around 250.8 billion cubic meters
Some 65 percent of fuel consumption in Iran belongs to gas; thus,
the daily gas consumption in the country is equivalent to consuming five million barrels of crude oil per day.
If we assume Iran's industry is 60% of Brazil's industry.
based on agriculture data plus industry it will make
Iran's GDP ~$1.62 T and
~$3.06 T for Brazil.(mostly 2020 data)
And I think 60% is not fair for Iran !
