    The perimeter of a floor of a room is 18 m. What is the area of four walls of the room, if its height is 3 m?

    A)  \[27\,\,{{\text{m}}^{\text{2}}}\]

    B)  \[54\,\,{{\text{m}}^{\text{2}}}\]

    C)  \[58\,\,{{\text{m}}^{\text{2}}}\]

    D)  \[64\,\,{{\text{m}}^{\text{2}}}\]

    Correct Answer: B

    Solution :

    Let length and breadth of the room be I and b. Then, perimeter \[=2\times (1+b)=18\] \[\therefore \]      \[l+b=9\] Area of four walls of the room \[\Rightarrow \]   \[2\times (l+b)\times h=2\times (9)\times 3=54\,\,{{\text{m}}^{\text{2}}}\]
