    let 9x = length let 5x = width perimeter =18x +10x =28x =112 in. x=4 9x=36 in. length 5x = 20 in width.

    112/2=56inches, this is the length and width add up together. 9+5=14, to see how many ratios are there. 56/14=4, this is one ratio. length is 5*4=20inches, width is 4*4=16inches

    Proof does the perimeter = 112 in. 36 + 36 +20 +20 =112 112=112 Checks/ Is there a ratio of 9 to 5? 36/20=9/5 checks. The answer is correct.
