    The measures (in cm) of sides of a right angled triangle are given by consecutive integers. Its area (in \[\text{c}{{\text{m}}^{\text{2}}}\]) is

    A)  9                                

    B)  8

    C)  5                                

    D)  6

    Correct Answer: D

    Solution :

    \[{{3}^{2}}+{{4}^{2}}={{5}^{2}}\] \[\therefore \]      Base \[=3\,cm,\] Perpendicular \[=4\,cm\] \[\therefore \] Area of the right angled triangle             \[=\frac{1}{2}\times \text{base}\times \text{height}\] \[=\frac{1}{2}\times 3\times 4=6\,\,sq\,cm\]
