    C 30 cm Correct Answer Incorrect Answer
    D 34 cm Correct Answer Incorrect Answer

    Solution

    Let the length and breadth of the rectangle be 5x cm and 4x cm, respectively According to the question, 2 × (5x + 4x) = 306 Or, x = 153/9 = 17 Therefore, each side of the square = 1.25 × 4x = 85 cm Perimeter of the square = 4 × 85 = 340 cm Required difference = 340 – 306 = 34 cm
