Question

Спортивная площадка имеет форму прямоугольника. В таблице указаны её площадь и ширина. Чему равна длина площадки? Площадь прямоугольника-800 м квадратных, ширина-200 дм, длина-?

Answer 1

1м = 10 дм
200дм = 20м
800 : 20 = 40м
40м = 400дм
Ответ: 400 дм или 40 м.

Answer 2

Calculation of the Length of the Sports Field

To calculate the length of the sports field, we can use the formula for the area of a rectangle:

Area = Length × Width

Given that the area of the sports field is 800 square meters and the width is 200 decimeters (dm), we can substitute these values into the formula:

800 = Length × 200

To find the length, we need to solve for it. We can do this by dividing both sides of the equation by 200:

Length = 800 / 200

Calculating this expression gives us:

Length = 4 meters

Therefore, the length of the sports field is 4 meters.
