Multiple Choice

The area of a square with side length s is:

Area is the amount of surface a shape covers. For a square, think of dividing it into s by s unit squares. There are s rows and s columns of these small squares, so you get s × s unit areas in total. That makes the area s^2. So a square with side length s has area s^2. Expressions like s^3 would describe volume (three-dimensional growth), not area. A linear expression like 2s isn’t measuring area at all, it’s just a length. And s^2 + s adds an extra linear term, which doesn’t match the actual area of a square.
