Question

A rectangular yard has a total perimeter of 220 feet. The widths of the yard are each 30 feet shorter than the lengths of the yard. What are the dimensions of the yard?

Answer 1

L = 70 W = 40

Explanation:

P = 220 ft

W = L - 30

I started guessing numbers for L that would work. When I did this, I made sure that all of the sides added up to 220 ft.
