The side of a square is 4 cm. It is cut into 4 equal squares. What is the area of each small square?

The original square has side 4 cm, so its area is 4 × 4 = 16 cm². When cut into 4 equal squares, each small square has area = 16/4 = 4 cm². The side of each small square would be 2 cm (since the original 4 cm side is divided into 2 equal parts to create 4 squares in a 2×2 arrangement), and 2 × 2 = 4 cm².
