    The third side of the triangle if the perimeter of a triangle is 20m and two of its sides are 5m and 4m, is

    A) 11 m     

    B) 10m          

    C) 12m                            

    D) 5m

    Correct Answer: A

    Solution :

    Perimeter of a triangle \[={{1}^{st}}side+{{2}^{nd}}side+{{3}^{rd}}side\] So, \[20=5+4+{{3}^{rd}}\]side \[{{3}^{rd}}side=20-9=11m.\]
