Area info

Area is the measure of a flat space or surface and determines the extent of 2-D and 3-D objects. For that reason, the SI unit (International System of Units) for area is square meter (m2).

The area of quadrilaterals equals the multiplication of the length and the height. Furthermore, all polygons can be broken down into triangles. Therefore, 1/2 * length * height formulates the area of a triangle, and so all polygons. Also, the well-known formula πr2 calculates the area of a circle.

When calculating surface areas, the object can be theoretically cut and flattened out. This creates a 2-D shape from which the final value can be derived.

The acre is a non-metric unit that is equal to 43,560 square feet or 1/640 square miles. The unit forms part of both the imperial and US customary system. Supposedly, the measurement originates from amount of land that a yoke of oxen could plough in one day.

The hectare, however, is a metric unit that is equal to 10,000 square meters or 100 ares, which is largely defunct. Therefore, it is itself a hundredth of a square kilometer. In contrast to the are, the hectare is the most common land measure around the world.
