Final answer:
The area of a square is equal to the length of one side squared.
Step-by-step explanation:
The correct answer is A) The area is equal to the length of one side squared. The area of a square is calculated by multiplying the length of one side by itself. This is because all sides of a square are equal in length. So, if the length of one side is 's', the formula for the area of a square is 's x s' or 's2'.
