Question 1045007: The perimeter of a slandered-sized rectangular rug is 40 ft. The length is 2 ft longer than the width. Find the dimensions. Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! Perimeter = 2L+2W (1)
and the problem says that:
L = W+2 (2) Substitute in (1)
2(W+2)+2W = 40
2W+4+2W = 40
4W = 36
W = 9 This is the width, and the length is 9+2 = 11
-----------------------
Check:
2(11)+2(9) = 40
22+18 = 40 Correct
