Answer 6

Since length is twice the width, you can substitute length like this.
P = 2L + 2W
Since, L = 2W
P = 2(2W) + 2W
Solve for W, that'll give you the width. And you can find the length. c:

Answer 13

P = 2*length + 2*width
Replace 'length' with '2*width'
P = 2*(2*width) + 2*width
P = 4*width + 2*width
P = 6*width
You're given the perimeter. Solve for width.
