The length of a rectangle is 2 feet more than its width. If it’s perimeter is 40 feet, what is the measure of the length and the width?

Question

I was working on my math homework review and this question popped up and I got really confused I need help with work involved

Answer 1

Perimeter = 2 * length + 2 * width

Length L = w+2 where w is the width

40 = 2 ( w + 2) + 2*w

40 = 2w + 4 + 2w

40 + 4w + 4

36 = 4w

w = 9

width is 9 and length is 11
