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.
Rectangle ABCD shares BC with equilateral triangle BCE. The length of CD is 4cm, and the length of DA is 3cm. What is the length of BE?
