    Question

    A square’s side length is equal to the radius of a

    circle, whose area is 2464 m². Determine the perimeter of the square.
    A 125 m Correct Answer Incorrect Answer
    B 188 m Correct Answer Incorrect Answer
    C 170 m Correct Answer Incorrect Answer
    D 112 m Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the radius of the circle be ‘r’ m

    π × r² = 2464

    (22/7) × r² = 2464

    r² = 784

    r = 28

    Since the side length of the square = radius of the circle = 28 m

    Perimeter of the square = 4 × 28 = 112 metres
