    The sum of interior angles of a regular polygon is\[2520{}^\circ \], then what is the number of sides in that polygon?

    A)  8                                

    B)  16

    C)  32                               

    D)  12

    Correct Answer: B

    Solution :

     The sum of interior angle of regular ploygon is \[=\,(n-2)\times 180{}^\circ \] \[(n-2)\times 180{}^\circ =2520{}^\circ \] \[\Rightarrow \,\,\,n-2=\frac{2520}{180}=14\] \[\therefore \,\,\,n=14+2=\underline{\mathbf{16}}\]
