      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
