    If the area of a triangle with base 12 cm is equal to the area of a square with side 12 cm, the altitude of the triangle will be

    A) 12 cm

    B)  24 cm

    C)  18 cm

    D)  36 cm

    Correct Answer: B

    Solution :

    Area of square \[={{(12)}^{2}}=144\,\,c{{m}^{2}}\] Area of triangle \[=\frac{1}{2}\times \text{Base}\times \text{Height}\] \[=\frac{1}{2}\times 12\times \text{Height}\] \[\Rightarrow \]   \[\frac{1}{2}\times 12\times \text{Height=144}\] \[\Rightarrow \]   Height \[=\frac{144\times 2}{12}=24\,\,\text{cm}\]
