Five squared

It is named this because squaring a number gives the area of a square.

Squaring a number can also be written as 6² = 36. Squaring is the same as raising to the power of 2.

Many of the units of area are squares. For example, a square meter means the area equal to the area of a rectangle which is one meter tall and one meter wide.
