Suppose the width of a rectangle is 5 inches shorter than the length and that the perimeter of the rectangle is 80 inches. The formula for the perimeter of a rectangle is P=2L + 2W. Set up an equation for the perimeter involving only the L the length of the rectancle.

And solve this linear equation algebracially to find the length of the rectangle and find the length as well

    W+5=L-5
    P=2W+2L=80

    2(L-5)+2L=80
    you finish it.
