Let the side of the inscribed square be 12 cm. The diagonal of the square will be equal to the diameter of the circle. Diagonal of the inscribed square = √2 × side = √2 × 12 = 12√2 cm. The radius of the circle = (12√2) / 2 = 6√2 cm. For the circumscribed square, the side of the square is equal to the diameter of the circle, which is 12√2 cm. Area of the inscribed square = (12)² = 144 cm². Area of the circumscribed square = (12√2)² = 288 cm². Difference in areas = 288 - 144 = 144 cm². Correct Option: c
