Explain the relationship between direct square variation and the area of a square.

The area of a square is unrelated to its side length

The area of a square is inversely proportional to the square of its side length

The area of a square is directly proportional to its side length

The area of a square is directly proportional to the square of its side length, which means that as the side length increases, the area also increases by the square of the side length.
