Question 421802
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
