    The perimeter of a rectangular picture is 160 cm. It is 30 cm wide. How long is it?

    A)  \[5\frac{1}{3}\]cm                   

    B)  50 cm

    C)  100 cm                        

    D)  130 cm

    Correct Answer: B

    Solution :

     Perimeter \[=160\,cm\] Breadth \[=30\text{ }cm\] \[\therefore \] 2(Length + Breadth) = 160 cm \[\Rightarrow \] 2(Length + 30 cm) = 160 cm \[\Rightarrow \] Length \[+30\,cm=80\,cm\] \[\Rightarrow \] Length \[=(80-30)\,cm=50\,cm\]
