What is the formula for the area of a square?

The formula for the area of a square is expressed as A = s², where "s" represents the length of one side of the square. This formula captures the concept that the area of a square is determined by squaring the length of one of its sides. Since all sides of a square are equal, multiplying the length of one side by itself gives the total area enclosed within the square's four equal sides.

Understanding the components of the formula is crucial. Given that a square has four right angles and all sides are congruent, squaring the side length effectively calculates the total space the square occupies in a two-dimensional plane.

Other formulas mentioned relate to different geometrical shapes or dimensions; for instance, A = lw is the formula for the area of a rectangle, A = bh pertains to the area of a triangle, and A = 1/2bh is also a triangle formula. These respective formulas cannot apply to a square, owing to the unique properties of squares where all sides are equal. Thus, the correct formulation for the area of a square is indeed A = s².
