The length of a rectangle is twice its width. The perimeter of the rectangle is 126 feet. (Write the equation) i've already tried to divide 126 by two which gave me 63 but i didn't know what to do with the 63.

3 answers

P = 2L + 2W

126 = 2(2W) + 2W

126 = 6W

21 = W

L = 2 * 21

L = 42

7470

Is dat the right answer
