The diameter of the circle is 14 cm, so its radius is 7 cm. The diagonal of the smaller square is equal to the diameter of the circle, which is 14 cm. Using the formula for the diagonal of a square (d = a√2), where a is the side of the square, we find that the side of the smaller square is a = 14/√2 = 7√2. Area of smaller square = (7√2)² = 98 cm². Area of larger square = 14² = 196 cm². Area of the region = 196 - 98 = 98 cm². Correct answer: a) Area of smaller square = 98 cm², Area of region = 98 cm²
