1. Are the sides of triangle BCE, BC, BE and EC ?

In rectangle ABCD, is side BC opposite to side AD? If so, AD = BC = 3

If so, since BCE is an equilateral triangle, (all three sides equal)therefore BE = BC = EC = 3.

I don't have the advantage of seeing the diagram you are, so you will have to decide if my logic is correct.
