    The given figure is made up of a triangle and a square of area\[144\,\,c{{m}^{2}}\]. What is the perimeter of the figure?

    A) \[72\,\,cm\]                   

    B)           \[60\,\,cm\]                   

    C)           \[360\,\,cm\]                  

    D)           \[12\,\,cm\]

    Correct Answer: B

    Solution :

                Area of square \[=144\,\,c{{m}^{2}}\] \[\therefore \]Its side\[=12\,\,cm\] Hence, the required perimeter             \[=5\times 12\,\,cm=60\,\,cm\]
