Examples • A company in Dallas, Texas makes ceramic tile that is used to cover floors or walls. Find the area of a ceramic tile that needs to be glazed if it is shaped like a parallelogram with the height of 4 ½ inches and a base of 6 ¾ inches. Use the formula for the area of a parallelogram to find the area of the top of the tile.
