Question: how do you work out the size of a room in square metres?
Answer: Now that you know the room's length and width in meters, you calculate its area using the formula length × width = area. If the room is 4 meters long and 3 meters wide, its area is 4 meters × 3 meters = 12 square meters. If the room is 6 meters long and 5 meters wide, its area is 6 meters × 5 meters = 30 square meters.
