Question 411216: Suppose that the width of a rectangle is 5 inches shorter than the length and that the perimeter of the rectangle is 50 inches. Thw formula for the perimeter of a rectangle is P=2L+2W. Set up an equation for the perimeter involving only L, the length of the rectangle. Solve this equation algebraically to find the length of the rectangle. Find the width as well.
