B Correct answer
Explanation

The radius of the circle is half of its diameter, which is 14 cm. The area of the circle is calculated as pi * r^2, which equals (22/7) * 14 * 14 = 616 square centimeters. Since the area of the square is equal to the area of the circle, the area of the square is also 616 square centimeters.

AI explanation

The area of the circle is found using the formula pi * r^2, where the radius is half of the 28 cm diameter, giving an area of 22/7 * 14 * 14 = 616 cm2. Because the area of the square is equal to the area of this circle, the area of the square is also 616 cm2.
