What is the area of a square with sides of length 4?

• A. 8
• B. 12
• C. 16
• D. 20

Answer: (C)

To find the area of a square, you can use the formula: Area = side length × side length. In this case, the length of each side of the square is given as 4 units. Plugging this into the formula: Area = 4 × 4 = 16 square units. Therefore, the area of the square is 16, confirming that the correct answer is accurate. Knowing this formula can be very helpful because it applies universally to any square, regardless of the side length. This formula is derived from the properties of squares, where all sides are equal in length, making the calculation straightforward.
