    The diagonal of a square is \[4\sqrt{2}\,cm\]. The diagonal of another square whose area is double that of the first square, is

    A)  \[8\sqrt{2}\,cm\]                       

    B)  \[16\,cm\]

    C)  \[\sqrt{32}\,cm\]                       

    D)  \[8\,cm\]

    Correct Answer: D

    Solution :

    Length of diagonal of square \[=452\,cm\] \[\therefore \]      Side of square \[=4\,cm\]                \[\therefore \]      Area of square \[=16\,c{{m}^{2}}\]            \[\therefore \] Area of another square \[=32\,c{{m}^{2}}\] \[\therefore \]      Side of this square \[=\sqrt{32}=4\sqrt{2}\]      \[\therefore \]      Diagonal of this square \[=4\sqrt{2}\times \sqrt{2}=8\,cm\]
