Answer by macston(5194) (Show Source): You can put this solution on YOUR website!
L=length (Parallel to wall); W=width (Perpendicular to wall); A=area=750m^2
L+2W=80m
L=80m-2W
A=L*W Substitute for L

Subtract 750m^2 from each side.
Multiply each side by (-1/2)

or ANSWER 1: The width is 15 meters.(or 25m)
L=80m-2W=80m-2(15m)=80m-30m=50m ANSWER 2: The length is 50 meters.(or 30m)
