  • Paper

The diameter AB‾\overline{AB} of a circle of radius 22 is extended to a point DD outside the circle so that BD=3BD=3. Point EE is chosen so that ED=5ED=5 and line EDED is perpendicular to line ADAD. Segment AE‾\overline{AE} intersects the circle at a point CC between AA and EE. What is the area of △ABC\triangle ABC?
