bob needs 60 square feet of cloth. He has a rectangular piece of cloth that measures 3 feet by 9 feet and a square piece that measures 5 feet on a side. Does he have enough cloth? If not, how much more does he need?
47 sq ft of cloth. Needs 60 so she needs 13 more sq ft of cloth ????
9 * 2 = 27
5 * 5 = 25 !!!!!
but still not enough :)
