I am terrible at ellipse
The base of an auditorium is in the form of an ellipse 200ft long and 100 ft wide. A pin dropped near one focus can clearly be heard at the other focus. Determine the distance between the foci to the nearest tenth of a foot. Show each step.

You have
a = semi-major axis = 100
b = semi-minor axis = 50
a^2 = b^2+c^2
where c is the distance from the center to the focus.
Find c, and then the distance between the foci is 2c.
