the long is 25 feet long which means that our major axis(a) is 44 feet.
the maximum height of the ceiling is 22 feet which mean that this is the measure of the minor axis (b)
the foci are located at (hīc.k),and we can set the center at (0.0),we can get c from the formula a a²-b²=c²(which is a given for all ellipses).
a=44ft,b=22ft c
