Question

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

Answer 1

length=72

width=63

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)
