Question

The width of a rectangle is 9
inches less than the length. The
perimeter is 86 inches

Answer 1

Below.

Explanation:

If the length is x then the width is x-9 inches.

Perimeter

= 2L + 2W = 86

2x + 2(x - 9) = 86

4x - 18 = 86

4x = 104

x = 26

So the length is 26 inches and the width is 17 inches.
