1. Find the length of the rectangle A= 63 square ft. w= 7 ft. A= l x w 63= l x 7 (Think: If l= 63/7) l= 9 So the length is 9 ft. 2. Find the width of the rectangle P= 30in. l=11in. P=2l+2w 30=2(11) + 2w 30=22+2w (Think: If 30=22+2w, then 2w=30-22) 2w=12 (Think: If 2 x w=8, then w= 8/2) w=4 So the width is 4 inches
