Which unit is commonly used to measure area?

Area is a measure of the extent of a two-dimensional surface and is expressed in square units. The standard unit for measuring area in the metric system is the square meter. A square meter represents a square that is one meter on each side. This unit is fundamental in various fields, including construction, land measurement, and agriculture, where understanding the area is essential for estimating space and resources.

Other units mentioned, such as liters, grams, and seconds, measure volume, mass, and time, respectively, which do not relate to area measurement. Liters measure how much space a liquid occupies, grams quantify mass, and seconds track intervals of time. Therefore, the only unit that aligns with the definition and application of area measurement is the square meter.
