Question

Фермер засеял пшеницей половину поля прямоугольной формы длиной 400 метров и шириной 200 метров. Сколько гектаров этого поля заняла пшеница?

Answer 1

1га=10000м²

400*200=80000м² все поле

80000/2=40000м²=4га половина поля засеянная пшеницей

Answer 2

400*200=80000м2=8га (общая площадь поля)

 

8:2=4га (гектаров єтого поля заняла пшеница)

Answer 3

Calculation of the Area of the Wheat Field

To calculate the area of the wheat field, we need to multiply the length by the width of the rectangular field. In this case, the length is given as 400 meters and the width is given as 200 meters.

The formula to calculate the area of a rectangle is:

Area = Length x Width

Substituting the given values:

Area = 400 meters x 200 meters

Now, let's calculate the area:

Area = 80,000 square meters

Conversion to Hectares

To convert the area from square meters to hectares, we need to divide the area by 10,000. This is because there are 10,000 square meters in one hectare.

Using the calculated area of 80,000 square meters:

Area in Hectares = 80,000 square meters / 10,000

Now, let's calculate the area in hectares:

Area in Hectares = 8 hectares

Therefore, the wheat field occupied 8 hectares of the total area.
