Area is the measurement of the two-dimensional space enclosed within a shape or surface. It represents how much surface a flat object occupies and is expressed in square units such as square meters (m²), square feet (ft²), acres, and hectares. Area measurement is fundamental in mathematics, engineering, architecture, construction, agriculture, real estate, land surveying, and environmental planning.

Different countries and industries use different area units depending on local standards, regulations, and practical requirements. The square meter (m²) is the internationally accepted SI-derived unit of area, while square feet (ft²) are widely used for residential and commercial properties in the United States and several other countries. Larger land areas are commonly measured in hectares, acres, or traditional regional units.
