The area of square WXYZ is 25 cm^2. The four smaller squares have sides 1 cm long. In triangle ABC, AB=AC. When triangle ABC is folded over line BC, point A coincides with O, the center of square WXYZ. What is the area of triangle ABC.
I got \(\displaystyle 3.5^2\)
is this right or wrong, plus can someone help me clarify it a bit?[/i]
