The area of the rectangle, one side 8 cm, is equal to 72 cm2. Find the perimeter of this rectangle.

By condition, the area of the rectangle is 72 cm2.

The area of the rectangle is equal to the product of the length and the width.

Let’s denote by x cm – the width of the rectangle, according to the condition 8 cm – the length of the rectangle.

72 = 8 * x;

x = 9 (cm).

To find the perimeter of a rectangle, you need to find the sum of all the sides. In a rectangle, opposite sides are equal.

Find the perimeter of the rectangle:

9 + 9 + 8 + 8 = (9 + 8) * 2 = 34 cm.

Answer: 34 cm.
