---
Perimeter = 2(width + length)
Let width = x
Then length = 2x+9
--------
174 = 2(x + 2x+9)
87 = 3x+9
3x = 78
x = 26
----
Width = 26 meters
Length = 2x+9 = 52+9 = 61 meters

You can put this solution on YOUR website! Solutions: Let the width be "x"
and the length be 9+2w
Given:Perimeter=174 meters
we know Perimeter of rectangle=2L + 2W
P=2Lx 2W
174=2(9+2w) + 2w
174=18 +4w +2w
174=18+6w
6w=174-18
6w=156
w=156/6
w=26
Therefore Width=26 meter
Length=9+2w=9+2x26
=9+ 52
=61 meter
