About Area Measurement
Area is the measure of the size of a two-dimensional surface. It's calculated by multiplying length by width for rectangles, or using different formulas for other shapes. Area units are derived by squaring length units.
Hectares and Acres
Hectares and acres are commonly used for measuring land. A hectare (10,000 m²) is slightly smaller than 2.5 acres. Hectares are used in most countries, while acres are common in the US, UK, and countries using imperial measurements.
