    Three sides of a triangular field are of length\[15\text{ }m\]. \[20\text{ }m\]and \[25\text{ }m\]long respectively. Find the cost of sowing seeds in the field at the rate of 5 rupees per sq. m.                                 

    A)  Rs.300                       

    B)  Rs.600

    C)  Rs.750           

    D)       Rs.150

    Correct Answer: C

    Solution :

     \[{{15}^{2}}+{{20}^{2}}={{25}^{2}}\] \[\therefore \] The triangular field is right angled. \[\therefore \] Area of the field \[\frac{1}{2}\times 15\times 20=150\,sq.\] metre \[\therefore \] Cost of sowing seeds \[=150\times 5=Rs.\text{ }750\]
