    Question

    A square has a side length equal to the radius of a circle

    whose area is 201.96 m². Calculate the perimeter of the square.
    A 32 m Correct Answer Incorrect Answer
    B 44 m Correct Answer Incorrect Answer
    C 20 m Correct Answer Incorrect Answer
    D 12 m Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the radius of the circle be ‘r’ m

    π × r² = 201.96

    (22/7) × r² = 201.96

    r² = 64

    r = 8

    Since the side length of the square = radius of the circle = 8 m

    Perimeter of the square = 4 × 8 = 32 metres
