Question

поле прямокутнои форми засияли пшеницею. Довжинна поля 800 м, що в 4 рази бильше ниж ширина. з усиеи дилянки зибрали 40 т. пшеници скильки центнерив пшеници зибрали з кошного гектара?

Answer 1

Поле прямоугольной формы засеяли пшеницей.
Длина поля 800 м, что в 4 раза больше ширины.
Со всего участка собрали 40т пшеницы. Сколько центнеров пшеницы собрали с каждого гектара?
------------------------------------------------------------
1 гектар - площадь участка, равная площади 100 м*100 м=10 000 м²
1 тонна = 1000 кг, 1 центнер = 100 кг, 1 тонна = 10 центнеров
--------------------------------------------------------
1)

Какова ширина поля?
800:4=200 (м)
2)

Какова площадь поля?
800*200=160000 м²
3)

Сколько га занимает поле?
160000 : 10 000=16 (га)
4)

Сколько центнеров пшеницы собрали с каждого гектара?
40т:16=400 ц:16=25 (ц)

Ответ: 25 центнеров собрали с каждого гектара

Answer 2

Calculation of Wheat Yield per Hectare

To calculate the yield of wheat per hectare, we need to determine the area of the field in hectares and the total amount of wheat harvested.

Given: - The length of the field is 800 meters. - The length is 4 times greater than the width. - The total amount of wheat harvested is 40 tons.

Let's calculate the width of the field first.

Step 1: Determine the width of the field. The length of the field is 4 times greater than the width. Let's assume the width of the field is "x" meters. Therefore, the length of the field is 4 times the width: 4x.

According to the given information, the length of the field is 800 meters. So we can set up the equation:

4x = 800

Step 2: Solve the equation for "x". Divide both sides of the equation by 4 to isolate "x":

x = 800 / 4 x = 200 meters

Therefore, the width of the field is 200 meters.

Step 3: Calculate the area of the field in hectares. To convert the area from square meters to hectares, we divide by 10,000 (since 1 hectare = 10,000 square meters).

Area = (length * width) / 10,000 Area = (800 * 200) / 10,000 Area = 16 hectares

Therefore, the area of the field is 16 hectares.

Step 4: Calculate the yield of wheat per hectare. To calculate the yield of wheat per hectare, we divide the total amount of wheat harvested by the area of the field.

Yield per hectare = Total amount of wheat harvested / Area of the field Yield per hectare = 40 tons / 16 hectares

Now, let's calculate the yield per hectare:

Yield per hectare = 40 / 16 Yield per hectare = 2.5 tons per hectare

Therefore, the yield of wheat per hectare is 2.5 tons.

So, from the given information, it can be concluded that they harvested 2.5 tons of wheat per hectare.
