Question

can someone help me understand this? The length of the rectangle is two more then its width. the perimeter of the rectangle is 72 meters. what is the length of the rectangle?

Answer 1

length = 24 meters

Explanation:

1. l = 2w

2. P = 2l + 2w

P=72

3. 72 = 2l + 2w

4. Substitute w=l/2 to solve for l

72 = 2l + 2(l/2) ---> 72 = 3L - Divide by 3 on both sides

L= 24 meters
