    The area of a rectangular field is 2100 square metres. If the field is 60 metres long, what is its perimeter?

    A)  180 metre                    

    B)  200 metre

    C)  240 metre         

    D)       None of these

    Correct Answer: D

    Solution :

     Breadth \[=\frac{Area}{Length}\]       \[=\frac{2100}{60}\] = 35 metre \[\therefore \] Perimeter = 2 (Length + breadth)                     \[=2(60+35)=190\] metre
