The area of a rectangle, one side of which is 4 cm, is equal to 36 sq. Cm. Find its perimeter.

We have a rectangle with known area and width. Find the perimeter of the rectangle.

The area of a rectangle is the product of the width and length of the rectangle.

S = a * b;

a = S / b = 36/4 = 9 cm.

Perimeter is twice the sum of the length and width of the rectangle.

P = 2 * (a + b) = 2 * (9 + 4) = 26 cm.
