A square is a rectangle with all sides equal. A square with side a has perimeter 4a and area a2.

The square is used as the unit of area; that is, a figures area is expressed as the number of equal squares of some standard, such as square inches or square meters, that the figure can contain. In Greek geometry, the area of a figure was determined by converting the figure to a square of the same area. This is easily accomplished for triangles, rectangles, and other polygons, but is often impossible for other figures, such as circles.
