Question

Сквер имеет прямоугольную форму.Его длина =50м.Ширина 20м. 2\5 площади сквера занимает детская площадка,а остальное под деревья отведено место.Найти площадь отведёную под деревья.

Answer 1

50*20=1000 м2 площадь сквера
1000/5*2=400 м2 занимает детская площадка
1000-400=600м2 площадь под деревья

Answer 2

Calculation of the Area for Trees in the Square

To find the area allocated for trees in the square, we need to subtract the area occupied by the children's playground from the total area of the square.

Given: - Length of the square = 50m - Width of the square = 20m - 2/5 of the square's area is occupied by the children's playground.

To calculate the area of the square, we can use the formula: Area = Length x Width.

Let's calculate the area of the square first: - Length = 50m - Width = 20m

Area of the square = 50m x 20m = 1000 square meters.

Now, let's calculate the area occupied by the children's playground: - 2/5 of the square's area is occupied by the children's playground.

Area of the children's playground = (2/5) x 1000 square meters = 400 square meters.

To find the area allocated for trees, we need to subtract the area of the children's playground from the total area of the square:

Area allocated for trees = Total area of the square - Area of the children's playground = 1000 square meters - 400 square meters = 600 square meters.

Therefore, the area allocated for trees in the square is 600 square meters.
