What is the area of a square room that is 10 meters in length and 10 meters in width?
100 square meters, which is the product of the length and width of the room.
1000 cubic meters, assuming a height of 10 meters, which is not relevant for area calculation.
10 square meters, which would be incorrect as it does not account for the full dimensions of the room.
100 cubic meters, which is a volume measurement and not applicable to area.
What is the base unit for measuring area?
Square meter (m²) - the SI derived unit for area, representing the area of a square with sides of one meter in length.
