You can put this solution on YOUR website!
Let x= width of the rectangle
5x= length of the rectangle

2(W) + 2(L) = P
2(x) + 2(5x)=240
2x+10x=240
12x=240
x=240/12=20 cm. Width
5x=5(20)=100 cm. Length

Check: 2*20+2*100=40+200=240 It checks!

A rectangle is five times as long as it is wide. If the perimeter of the rectangle 240cm, write an equation and solve it to find its length and width.
let width be xcm
length = 5x
..
Perimeter = 2L+2W
240=2x+2*5x
240 =12x
x=20 the width
length = 5x= 100 cm
