Ben is setting up a tent. The sides that slope to the ground each measure 5.25 feet. If the sides and the ground form a triangle, what is the range of possible lengths for the base?

Answer 1

Consider the tent laid out flat. It would be 10.5 feet across.
So, as long as the base is less than that, the sides have to fold up.

Extra credit: considering the size of a person sleeping under the tent, what is a more reasonable restriction?
