    The area of a rhombus is \[150\,\,\text{c}{{\text{m}}^{\text{2}}}\text{.}\]The length of one of its diagonals is 10 cm. The length of the other diagonal is

    A) 25 cm

    B)  30 cm

    C)  35 cm

    D)  40 cm

    Correct Answer: B

    Solution :

    If \[{{d}_{1}},\]\[{{d}_{2}}\]be the diagonals of a rhombus, Area\[=\frac{1}{2}{{d}_{1}}\cdot {{d}_{2}}\] \[\Rightarrow \]   \[150=\frac{1}{2}\times 10\times {{d}_{2}}\]\[\Rightarrow \]\[{{d}_{2}}=\frac{150}{5}=30\,\,\text{cm}\]
