    One side of a parallelogram is 2.4 dam and its area is 576 m2. Find the corresponding altitude.

    A)  \[24\text{ }m\]                 

    B)         \[24\text{ c}m\]

    C)  \[24\text{ d}m\]             

    D)         \[24\text{ da}m\]

    Correct Answer: A

    Solution :

       2.4 dam \[=2.4\times 10=24\,m\] (Since 10 m = 1 dam.) We have, area \[=576\text{ }{{m}^{2}}\] \[\Rightarrow \] \[24\times \] altitude = 576 \[\therefore \]altitude  \[=\frac{576}{24}=24\,m\]
