the length of a rectangle is 9 cm more than the width the perimeter is 270 cm find the length and the width

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)
