    The breadth of a rectangle is w cm and the length is 5 times as long as its breadth. What is the perimeter of the rectangle?

    A)  \[5{{w}^{2}}cm\]

    B)  \[12w\,\,cm\]

    C)  \[(10+2w)cm\]

    D)  \[(25+{{w}^{2}})cm\]

    Correct Answer: B

    Solution :

    We have, breadth = w cm \[\therefore \] Length \[\text{= }5w\text{ }cm\] So, perimeter\[=2(5w+w)=2\times 6w\] \[=\text{ }12w\text{ }cm\]
