Question

Ширина прямоугольника площадки 30м. чему равен периметр площадки, если её площадь равна 2400м

Answer 1

S=a·b, где a и b - стороны прямоугольника,

отсюда a=S:b

1) 2400:30=80 (м) - длина

Р=2(а+b)

2) 2·(80+30)=2·110=220 (м) - периметр

Answer 2

Calculating the Perimeter of a Rectangle

To calculate the perimeter of a rectangle, we can use the formula:

Perimeter = 2 * (length + width)

Given that the width of the rectangle is 30m and its area is 2400m, we can calculate the length of the rectangle using the area and then find the perimeter.

Calculating the Length of the Rectangle

The formula for the area of a rectangle is:

Area = length * width

We can rearrange this formula to solve for the length:

length = Area / width

Substituting the given values: length = 2400m / 30m = 80m

Calculating the Perimeter

Now that we have the length and width of the rectangle, we can calculate the perimeter using the formula:

Perimeter = 2 * (length + width) Perimeter = 2 * (80m + 30m) Perimeter = 2 * 110m Perimeter = 220m

So, the perimeter of the rectangle is 220 meters.
