Answer by lwsshak3(6519)   (Show Source): You can put this solution on YOUR website!a rectangular lot whose perimeter is 220 feet is fenced along three sides. an expensive fencing along the lots lenght cost 20\$ per foot and the inexpensice fencing along the two side widths costs only 8\$ per foot. the total cost of the fencing along the three sides comes to \$2040. what are the lots dimensions? .. let W=width in feet let L=length in feet Then 2W+2L=220 or W+L=110 L=110-W Cost of 2 side widths=8*2W Cost of Length(one side)=20L=20(110-W) Total Cost=8*2W+20(110-W)=2040 16W+2200-20W=2040 -4W=2040-2200 4W=160 W=40 L=110-40=70 .. ans: The width of the lot=40 feet The length of the lot=70 feet
