Additional information
Area is a mathematical concept that refers to the measure of the size or extent of a two-dimensional surface. It quantifies the amount of space enclosed within a shape or region.
The standard unit of area in the International System of Units (SI) is the square meter (m2). The square meter represents the area of a square with sides measuring one meter. It is widely used in scientific, engineering, and everyday applications for measuring the extent or size of two-dimensional surfaces or regions.
The square meter can be further divided into smaller units, such as square centimeters (cm2) or square millimeters (mm2), for more precise or detailed measurements. Conversely, larger units like square kilometers (km2) or hectares (ha) are used to express larger areas, such as land areas or geographic regions.
In the US customary system, the most common units of area are square inches (in2), square feet (ft2), square yards (yd2), acres, and square miles (mi2).
