2) Carissa is building a new dining room table. The center of it is a rectangular section made from polished rocks. That section measures 36 in. by 64 in. She is also going to place wooden, eight-inch rectangular lip all the way around the perimeter. What is the area of the wooden part?

3) The Cowboy Ranch has a new owner. The 30 animals, all ostriches and horses, are dismayed, as they have heard that he is both foolish and inexperienced. Not being quite sure what he was looking for, however, he checked on the health of his animals by inspecting all of their feet. There were 96 feet in all. How many ostriches are there on this ranch?
