    The length and the breadth of a rectangular plot are in the ratio of 7 : 5. If the cost of fencing the plot @25 per metre is Rs.4800, what is the area of the plot? (in sq metre)

    A)  2240               

    B)  2142  

    C)    2269  

    D)    2025  

    E)    2340

    Correct Answer: A

    Solution :

    Let the length be 7x and the breadth be 5x. Now, the perimeter of the rectangle \[=\frac{4800}{25}=192\,m\] Then, 2(7x + 5x) = 192 or, 52x = 96 \[\therefore \]\[x=8\] Hence, length\[=7\times 8=56\,m\] Breadth \[=5\times 8=40\,m\] \[\therefore \] Area of the rectangular plate\[=56\times 40\] = 2240 sq m
