Answer by checkley71(8403)   (Show Source): You can put this solution on YOUR website!L=3W+8 PERIMETER=2L+2W 64=2(3W+8)+2W 64=6W+16+2W 64=8W+16 8W=64-16 8W=48 W=48/8 W=6 CM FOR THE WIDTH. L=3*6+8 L=18+8 L=26 CM FOR THE LENGTH PROOF 64=2*6+2*26 64=12+52 64=64 AREA=W*L AREA=6*26 AREA=156 CM^2 ANSWER FOR THE AREA.
