Question 980783: length of a rectangle is 5 inches longer than the width perimeter is 38 find the area Found 2 solutions by Cromlix, josgarithmetic:Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there,
Make width = x
Length then = 5 + x
Perimeter = 2 x Length + 2 x Width
38 = 2(5 + x) + 2(x)
38 = 10 + 2x + 2x
Collect like terms
2x + 2x = 38 - 10
4x = 28
x = 7
So, Width = 7 inches
and Length = 12 inches
Hope this helps:-)
