The formula for the area of a parallelogram is base*height. The question says that each tile has a piece of 0.28 and a height of 0.34 so it should be 0.28 * 0.34 which equals 0.952 meters^2. The total area of the floor should be 0.28 * 0.34 * 9500 with equals 904.4^2
Therefore, the answer should be C.
