Question

The length of a rectangle is 11 in. longer than its width. The perimeter of the rectangle is 86 in.

Answer 1

If your a visual person.

Answer 2

Let the width = x then length = x + 11 inches

Perimeter of a rectangle = 2*width + 2*length so we have the equation:-

( letting P = perimeter , L = length and W = width)

P = 2L + 2W

86 = 2(x + 11)) + 2x

86 = 4x + 22

4x = 86-22 = 64

x = 64 / 4 = 16 inches

Therefore the length of the rectangle = 16 + x

= 16 + 11 = 27 inches Answer
