this is what i have so far, but am stuck.
P=2L+2W
W=2L+3
P=2L+2(2L+3) Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! You're getting there but you only used half of the information.
"four times its lenght is twelve less than its perimeter"
Now you have another equation for P.
Put that together with your other equation for P.
Equate them and solve for L.
