A triangle corn field is 240 meters at the bottom and 150 meters high, with a total yield of 9360 kg. How many kg of corn per hectare on average? A triangle corn field is 240 meters at the bottom and 150 meters high, with a total yield of 9360 kg. How many kg of corn per hectare on average? (equation)

A triangle corn field is 240 meters at the bottom and 150 meters high, with a total yield of 9360 kg. How many kg of corn per hectare on average? A triangle corn field is 240 meters at the bottom and 150 meters high, with a total yield of 9360 kg. How many kg of corn per hectare on average? (equation)

According to the question, the area of triangle corn field is s = AB / 2, that is 240 * 150 / 2 = 18000 square meters
Because 1 hectare = 10000 square meters, the area of triangle corn field is 1.8 hectare
Total output value of corn / land area = output value per hectare
That is: 9360 / 1.8 = 5200ha / kg
A: slightly

In a newly reclaimed triangle land with a height of 30 meters and a bottom of 38 meters, 307.8 kg of corn was harvested. How many kg of corn was produced per hectare on average

The area of triangle land is 38 * 30 △ 2 = 570 square meters
1 ha = 10000 M2
So the area of the triangle is 0.057 hectares
The weight of corn per hectare is 307.8 △ 0.057 = 5400 kg

There is a triangle land, 150 meters long at the bottom and 420 meters high, with a total yield of 37800 kg of corn

If you know the length and height of the bottom, you can calculate the area
Triangle area = 1 / 2 * 150 * 420 = 31500 square meters = 3.15 hectares
15 = 12000 (kg)
