    The ratio of length and breadth of a rectangle is 5 : 4. If the breadth is 20 m less than the length then. Its perimeter is

    A)  280 m 

    B)  325 m

    C)  360 m 

    D)  380 m

    Correct Answer: C

    Solution :

    [c] Let length of rectangle = 5x Breadth of rectangle = 4x \[\therefore \] \[5x-4x=20\] x = 20 \[\therefore \] Length\[=5\times 20=100\,m\] Breadth\[=4\times 20=80\,m\] Perimeter\[=2(l+b)\] \[=2(100+80)=2\times 180\] = 360 m
