    Question

    The diagonals of a rhombus are 16 cm and 12 cm. What is

    the perimeter of the rhombus?
    A 40 cm Correct Answer Incorrect Answer
    B 48 cm Correct Answer Incorrect Answer
    C 52 cm Correct Answer Incorrect Answer
    D 56 cm Correct Answer Incorrect Answer

    Solution

    The diagonals of a rhombus bisect each other at right angles. The side of the rhombus = тИЪ[(16/2)┬▓ + (12/2)┬▓] = тИЪ[8┬▓ + 6┬▓] = тИЪ[64 + 36] = тИЪ100 = 10 cm. Perimeter = 4 * 10 = 40 cm.
