Area of a rectangle formula
l × w
6.5 is our width you already know but 53.3 isn't the length so really
you are trying to solve for l, so l × 6.5 = 53.3
when you get that answer you should get 8.2
Now .. you already have the width and the length so you hook in 6.5(w) + 6.5(w)+ 8.2 (l)+ 8.2(l)
6.5 + 6.5 gives you 13 and
8.2 + 8.2 gives you 16.4
Adding both up you get the final answer/ perimeter 29.4 inches
