Question 763456: The length of a rectangular jewelry box is 3 in more than twice the width. The perimeter is 36 in. Find the length and width
Answer by Cromlix(4381) About Me  (Show Source):
You can put this solution on YOUR website!
Width = x
Length = 3 + 2x
Perimeter = 2*length + 2*width
36ins = 2*(3 + 2x) + 2(x)
36ins = 6 + 4x + 2x
36ins = 6 + 6x
36ins - 6ins = 6x
6x = 30ins
x = 5ins.
Width = 5ins
Length = 13ins
Hope this helps.
