    The floor of a room measures 12 m by 10 m. A carpet is placed on the floor from wall to wall. What is the area of the carpet?

    A)   \[120\,{{m}^{2}}\]                  

    B)        \[1200\,m\]

    C)   \[120\,m\]                

    D)          \[1200\,{{m}^{2}}\]

    Correct Answer: A

    Solution :

     Length of the floor \[=12\text{ }m\] Breadth \[=10\text{ }m\] \[\therefore\] Area \[=12\times 10=120\text{ }{{m}^{2}}\] \[\therefore\] Area of the carpet \[=120\text{ }{{m}^{2}}\]
