A rectangular rug has a length that is three feet longer than its width. Its area is 130 square feet. What are its dimensions?
Width = W
Length = W + 3
Area of a rectangle equals W times L
A+=+W%2AL
A+=+W%28W%2B3%29=130
W%5E2%2B3W-130+=+0
%28W-10%29%28W%2B13%29=+0
Two solutions : W=10,-13
A negative width doesn't make sense so W=10, L=13
