A warehouse, whose dimensions are shown below, needs primer (a coating painted on to help protect a building). The front and back of the warehouse each have a rollup door measuring 22 ft by 25 ft. The side of the warehouse facing the parking lot has a window measuring 18 ft by 32 in and an entry door measuring 42 in by 8 ft. The other side of the warehouse has no window or door. Use the given information to answer the questions. Each tab shows a different view of the warehouse.
