Question 664765: The length of a rectangle is 16cm more than triple the width. the perimeter of the rectangle is 104cm. Find the length and the width Answer by Seutip(231) (Show Source):
You can put this solution on YOUR website! Let:
x - be the width
3x+16 - be the length
P - Perimeter (104cm)
l - length
w - width
P = 2l+2w
104 = 2(3x+16)+ 2(x)
104 = 6x+32+2x
104 = 8x+32
72 = 8x
9=x
