The area of a square is

• A. The length of the two sides multiplied by each other
• B. The length of one side multiplied by its width
• C. The perimeter of the square
• D. The length of one side squared

Answer: (A)

Area is found by multiplying side length by itself for a square. Since all sides of a square are the same length, multiplying the lengths of two sides gives the same result as squaring a single side. So, taking the length of one side and multiplying it by the length of another side yields the area because those two sides have equal length. The alternative phrasing “the length of one side squared” expresses the same idea more directly, but both describe the same area value. The essential rule to remember is area = side × side for a square.
