Hi,



The perimeter of a rectangle is 36 inches. 

If the length is 4 inches longer than the width, find the dimensions



Let x represent the width, then (x+4) is the length

Question states*****

 36 = 2(x+4) + 2x

Solving for x

2x + 8 + 2x = 36

4x = 28

x = 7in, the width.  The length is 11in  (x+4)

CHECKING our Answer***

 22in + 14in = 36in
