Question

PLEASE HELP!

Answer 1

If the length of the rectangle is 6 and the perimeter is 54, multiply the length by 6 and subtract the answer from 54. Then, divide the answer by 2 to get the width.

So, I will use your formula for this as it is correct:

2l+2w=54

2(6)+2w=54

12+2w=54

2w=42

42/2=21

w=21

Therefore, your length is 21. Hope this helps!
