You can put this solution on YOUR website! L=2W-3
2L+2W=18,000
2(2W-3)+2W=18,000
4W-6+2W=18,000
6W=18,000+6
6W=18,006
W=18,006/6
W=3,001 ANS. FOR THE WIDTH.
L=2*3,001-3=6,002-3=5,999 ANS. FOR THE LENGTH.
PROOF:
2*5,999+2*3,001=18,000
11,998+6,002=18,000
18,000=18,000
Answer by palanisamy(496) (Show Source):
You can put this solution on YOUR website! Let the width = x
Then its length = 2x-3
Perimeter is 2(x+2x-3) = 18,000
2(3x-3) = 18,000
6x-6 = 18,000
6x = 18006
x = 3001
Therefore the width = 3001 meters
Length = 2x-3 = 2*3001 - 3 = 6002 -3 = 5999
