    The length of two parallel sides of a trapezium are 15 cm and 20 cm. If its area is 175 sq. cm, then its height is:

    A)  10cm                         

    B)  15cm 

    C)         25cm              

    D)         20cm

    Correct Answer: A

    Solution :

    Area of trapezium \[=\frac{Sum\text{ }of\text{ }length\text{ }of\text{ }parallel\text{ }sides}{2}\times Height\,\,(H)\]\[175=\frac{15+20}{2}\times H\] \[H=\frac{175\times 2}{35}=10cm.\]
