How do you calculate the area of a square or rectangle?

• A. Base x Height
• B. Length x Width
• C. Pi x Radius Squared
• D. 2 x Length x Width

Answer: (B)

To find the area of a square or rectangle, multiply the two side lengths. For a rectangle, those sides are called length and width, so the area is length × width. A square is a special case where the two sides are equal, so it's the same idea (side × side). That’s why length × width is the standard and best answer. The circle area uses pi × radius squared, which isn’t relevant here. The expression 2 × length × width isn’t the area formula for these shapes. Base × height is a common formula for other shapes like parallelograms or triangles, but for rectangles we typically state it as length × width.
