    Question

    A square field has side 28 m. A circular lawn of radius

    14 m is made inside the field. Find the area of the remaining part of the field. (Use π = 22/7)
    A 115 m² Correct Answer Incorrect Answer
    B 168 m² Correct Answer Incorrect Answer
    C 133 m² Correct Answer Incorrect Answer
    D 147 m² Correct Answer Incorrect Answer

    Solution

    Area of square = side² = 28 × 28 = 784 m² Area of circular lawn = πr² = (22/7) × 14 × 14 = (22/7) × 196 = 22 × 28 = 616 m² Remaining area = area of square − area of circle = 784 − 616 = 168 m² Answer: 168 m².
