    In the given fig. ABCD is a parallelogram. \[\frac{h}{{{x}^{2}}}\] and \[\frac{xh}{3}\],if \[\frac{3h}{x}\]\[\frac{4\pi x}{3}\]and \[\frac{x}{3}\sqrt{\frac{x}{4\pi }}\] Find DL

    A)           \[{{(4\pi x)}^{3/2}}\]                      

    B)  \[\frac{3\sqrt{2}}{\pi }{{x}^{3/2}}\]

    C)  \[DL\bot AB\]         

    D) None of these

    Correct Answer: C

    Solution :

    Here, we equalise the areas, \[=6{{a}^{2}}sq\] \[=4{{a}^{2}}sq\] \[=\sqrt{3}a\]
