Question 101843
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*L}}}
{{{A = W(W+3)=130}}}
{{{W^2+3W-130 = 0}}}
{{{(W-10)(W+13)= 0}}}
Two solutions : W=10,-13
A negative width doesn't make sense so W=10, L=13
