Area

 Area, abbreviated as A, is a measure of the size of a two-dimensional surface or region.  The area of a shape can be found by multiplying the length of one side of the shape by the length of another side, or by using a formula specific to the shape.

Areas are used in many applications, including architecture, engineering, physics, and geography.  They are important for calculating quantities such as the amount of material needed to cover a surface, the amount of space available for construction, or the amount of energy absorbed by a surface.
