the perimeter of a rectangle is 56cm. The length of one side of the rectangle is 18cm. Find the area of the rectangle

Answer 1

The perimeter of a rectangle can be defined as P = 2W + 2L, where W is the width and L is the length. Substitute the given values into the equation and find the width, then use the length and width to find the area.

2W + 2(18) = 56

2W + 36 = 56

2W = 20

W = 10

Find the area using the formula A = W * L

A = W * L

= 10 * 18

= 180 cm
