Which formula represents the area of a square?

The area of a square is calculated by multiplying the length of one side by itself. This is represented mathematically as side squared. If the length of each side of the square is denoted as "s," the area can be expressed as ( A = s \times s = s^2 ).

This concept is rooted in the definition of a square, where all sides are of equal length and the area measures the amount of space within the boundaries of the square. Thus, expressing the area of a square as "side squared" accurately captures this relationship.

Other options suggest different calculations that apply to other shapes or measurements but do not correctly represent the area of a square. For example, multiplying by "height" or cubing the side length pertains to different geometric contexts, and simply doubling the side does not provide an area measurement. Thus, the formula representing the area of a square is effectively captured by the concept of side squared.
