SOLUTION

We want to find the distance that the top edge of the calendar is from the ceiling.

The diagram below will help us

From the diagram above x is the distance we want to find

We can see that the entire wall is 9 ft long,

Distance from the foot of the calender to the floor is 5 1/4 ft and

Halve of the calendar is 2/3 ft

So the whole calendar is


\begin{gathered} 2*(2)/(3) \\ =(4)/(3)\text{ ft } \end{gathered}

So, to find x, we will add length of the calendar which is 4/3 ft to distance from the foot of the calender to the floor which is 5 1/4 ft and subtract this from height of the wall which is 9 ft

We have


\begin{gathered} 9-((4)/(3)+5(1)/(4)) \\ 9-((4)/(3)+(21)/(4)) \\ 9-((16+63)/(12)) \\ 9-(79)/(12) \\ =(108-79)/(12) \\ =(29)/(12) \\ =2(5)/(12) \end{gathered}

Hence the answer is


2(5)/(12)\text{ ft}
