Question

Периметр прямоугольника равен 98 дм. длина 32 дм. Найди его площадь.

Answer 1

32*2=64(см)2 длины

98-64=34(см)2 ширины

34:2=17(см)ширина

32*17=544(см2)

Answer 2

32*2=64дм - 2 длины
98-64=34дм - 2 ширины
34/2=17дм - ширина
S=32*17=544дм²

Answer 3

Calculation of Rectangle Area

To find the area of a rectangle, we can use the formula: Area = length * width.

Given that the perimeter of the rectangle is 98 dm and the length is 32 dm, we can calculate the width using the formula for the perimeter of a rectangle: Perimeter = 2 * (length + width).

Let's calculate the width first:

Perimeter = 2 * (length + width)

98 = 2 * (32 + width)

Dividing both sides of the equation by 2:

49 = 32 + width

Subtracting 32 from both sides of the equation:

width = 49 - 32 = 17 dm

Now that we have the length and width, we can calculate the area:

Area = length * width

Area = 32 dm * 17 dm = 544 dm²

Therefore, the area of the rectangle is 544 square decimeters.

Answer

The area of the rectangle is 544 square decimeters.
