 Rectangles/77647: The width of a rectangle is 7 ft less than the length. The area of the rectangle is 120 ft2(square). Find the width of the rectangle.1 solutions Answer 55696 by prabhjyot(164)   on 2007-04-10 12:50:19 (Show Source): You can put this solution on YOUR website!The width of a rectangle is 7 ft less than the length. The area of the rectangle is 120 ft2(square). Find the width of the rectangle. If we let the length = L Then, the width, or w, will be L-7 We know that the area of a rectangle is length times width. So, L(L-7)=120 (L-15)(L+8) So, L=15,-8 length can't be negative, so L=15 So width w=L-7=15-7=8 So width of the rectangle is 8 ft.
