Question 795263: the length of a rectangular mailing label is 4 cm less than twice the width. find the dimensions of the label if the perimeter is 46cm Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Width = x
Length = 2x - 4
Perimeter = 2*width + 2*length
46 = 2*x + 2*(2x - 4)
46 = 2x + 4x - 8
6x = 46 + 8
6x = 54
x = 9 cm
Width = 9 cm
Length = 14 cm.
Hope this helps.
