    The diagonals of a rhombus are 24 cm and 10 cm. The perimeter of the rhombus (in cm) is

    A)  68                               

    B)  65

    C)  54                               

    D)  52

    Correct Answer: D

    Solution :

    If di and\[{{d}_{2}}\]are the lengths of diagonals of a rhombus. Then, Perimeter \[=2\sqrt{d_{1}^{2}+d_{2}^{2}}=2\sqrt{{{24}^{2}}+{{10}^{2}}}\] \[=2\sqrt{576+100}=2\sqrt{676}=2\times 26=52\,\,cm\]
