Question 761128: The length of a rectangle is 3 times its width. If the length is increased by 2 inches and the width by 1 inch, the new perimeter is 62 inches. What is the width before the increase
Answer by Cromlix(4381) About Me  (Show Source):
You can put this solution on YOUR website!
Width = x
Length = 3x
New sizes
Width = x + 1
Length = 3x + 2
Perimeter = 2*length = 2*width
62 = 2(3x + 2)+ 2(x + 1)
62 = 6x + 4 + 2x + 2
62 = 8x + 6
8x = 56
x = 7
Width was 7 inches before increase.
Hope this helps.
