    Hi, I need help with the following problem....

    Ceiling Length is 7.91m

    2.40m of the ceiling length is 1.94m high
    5.51m of the ceiling Length is 2.46m high

    What is the 'average' ceiling height for the room?

    The average ceiling height is given by :

    <h>=\frac{2.46*5.51+1.94*2.40}{7.91}

    But I have no calculator here ~
