Question 627528
Let x = width
 so 2x = length

2x + 5 = new length
x - 3 = new width
Perimeter = 2(2x + 5) + 2(x - 3) = 52, divide both sides by 2.
              (2x + 5) + (x - 3) = 26
              3x + 2 = 26
              3x = 24
               x = {{{highlight(8)}}} is the width of the original rectangle
              2x = {{{highlight(16)}}} is the length of the original rectangle
