What is the formula for the area of a square?

The formula for the area of a square is found by taking the length of one side of the square and multiplying it by itself. This process is often referred to as "squaring the side." Since all sides of a square are equal in length, using "side squared" accurately describes this relationship mathematically.

In practical terms, if each side of the square measures "s" units, then the area (A) can be expressed as A = s × s, which simplifies to A = s². This formula reflects the fundamental property of squares that distinguishes them from rectangles, which require both length and width but are not uniform in the length of their sides.

Understanding this concept is essential in solving geometric problems related to squares, as it allows for quick area calculations based on simple measurements.
