You could let
x = length
and
y = width

Now...you are given two FACTS about the rectangle. One involves the perimeter, and one involves the area. See if you can use the variables defined above to write two equations.

If you are still having trouble, please repost showing your work, so we can see where your difficulties lie.

Re: Factoring word problem

Do you use the formula p=2l+2w and a= l X w
