Answer:

length=72

width=63

Step-by-step explanation:

Let us start by supposing the following:

w=w

l=9+w

2l+2w=p(perimeter)

2(9+w)+2*w=270

    2w+2w+18=270

            4w+18=270

                   4w=252

                     w=63

                      l=72

We used the perimeter formula, 2l+2w=P(perimeter)
