You have decided it is time for a new floor in the bathroom. You tear up the old tile and repair the subfloor. You then measure the floor and determine the dimensions are 8 feet 8 inches by 12 feet 9 inches. Use mixed numbers to express the dimensions of the bathroom in feet. Round each dimension of the bathroom to the nearest foot, and then estimate the area of the bathroom.
