For example, if a room is 4 meters wide and 5 meters long, the area of the room is 20 square meters. This measurement is often needed to determine the amount of floor covering that is needed. When the area of a room is known, an estimate of the cost of the floor covering is also possible. Multiply the carpet cost per meter by the area of the room. For instance, if carpet is \$30 per square meter, covering a 20-square-meter floor costs approximately \$600.
