**Ms. Sue**, Wednesday, June 23, 2010 at 9:08pmP = 2L + 2W

90 = 4W + 2W

90 = 6W

15 = W

Check:

15 + 15 + 30 + 30 = 90

**sha**, Wednesday, June 23, 2010 at 9:24pmi know 90 is the perimeter but where did the 4W + 2W come from?

**Ms. Sue**, Wednesday, June 23, 2010 at 9:25pmThis is the formula for a perimeter.

P = 2L + 2W

Your problem states that the length is twice the width. Therefore, L = 2W
