Which formula gives the area of a square?

• A. L x L = A
• B. W x H = A
• C. L x W = A
• D. A = L + W

Answer: (A)

Area of a square is found by squaring the side length. Since all sides of a square are equal, if the side is labeled length L, the area is L × L, which is written as A = L × L. This captures both dimensions of the square in one product. The other formulas apply to rectangles or mix in addition: width times height gives a rectangle’s area, and length times width also describes a rectangle’s area when length and width may differ. Adding length and width does not yield area.
