    respectively. If the length is increased by 20% and the width is decreased by 10%, what will be the perimeter of the resulting rectangle?
    A 160.2 cm Correct Answer Incorrect Answer
    B 125.2 cm Correct Answer Incorrect Answer
    C 139.2 cm Correct Answer Incorrect Answer
    D 179.2 cm Correct Answer Incorrect Answer
