Question 1067389: What are the length and width of a rectangular traffic sign if the length exceeds the width by 11 inches and the perimeter is 118 inches? Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! 2Length + 2Width = perimeter
Length = W+11 substitute for L above:
2(W+11)+2W = 118
Apply distributive laws of multiplication:
2W+22+2W = 118
4W = 96
W = 24
L = 24+11 = 35

Check:
2L+2W = 118
2(35)+2(24) = 118
70+48 = 118 Correct
