    In the figure, ABCD is a trapezium in which AB = 15 cm, DC = 9 cm and DE = 8 cm. The area of ABCD is:

    A)  \[128\,c{{m}^{2}}\]                       

    B)  \[25\,c{{m}^{2}}\]

    C)  \[96\,c{{m}^{2}}\]             

    D)  \[216\,c{{m}^{2}}\]

    Correct Answer: C

    Solution :

        Area of trapezium ABCD \[=\frac{1}{2}\times (AB+DC)\times DE\] \[=\frac{1}{2}\times (9+15)\times 8=96\,c{{m}^{2}}\]
