Question

Ширина прямоугольного поля равна 400 метров, а длина поля - в два раза больше. Это поле засеяли картофелем и осенью собрали в среднем по 32 тонны картофеля с гектара. Сколько картофеля собрали со всего поля?

Answer 1

S = a * b - формула площади прямоугольника
1 га = 10 000 кв.м
------------------------------------
1) 400 м * 2 = 800 (м) - длина поля
2) 400 м * 800 м  = 320 000 (кв.м) = 32 (га) - площадь поля 
3) 32 га * 32 т = 1 024 (т) - урожай картофеля со всего поля
Ответ: 1 024 тонны картофеля.

Answer 2

Calculation of Potato Yield

To calculate the total amount of potatoes harvested from the entire field, we need to determine the total area of the field and then multiply it by the average potato yield per hectare.

Given information: - Width of the rectangular field: 400 meters - Length of the field: twice the width (800 meters) - Average potato yield per hectare: 32 tons

Calculation Steps:

1. Calculate the area of the field: - Area = Length × Width - Area = 800 meters × 400 meters - Area = 320,000 square meters

2. Convert the area from square meters to hectares: - 1 hectare = 10,000 square meters - Area in hectares = Area in square meters ÷ 10,000 - Area in hectares = 320,000 square meters ÷ 10,000 - Area in hectares = 32 hectares

3. Calculate the total amount of potatoes harvested from the entire field: - Total potato yield = Average potato yield per hectare × Area in hectares - Total potato yield = 32 tons/hectare × 32 hectares - Total potato yield = 1,024 tons

Therefore, the total amount of potatoes harvested from the entire field is 1,024 tons.
