Calculating the Area of a Square:

The area of a square with a known side length can calculated using the following formula:

A = a^2

The symbol ^2 means to square the item preceding it, in this case the side length (a). To square the side length multiply it by itself: a * a.

Below is an example of how to find the area of a square with the side length of 3.

  • A = a^2
  • = 3 * 3
  • = 9
