What is the area of the triangle BCD? (Diagram shows BCD on the base of a figure that looks like a Trapezoid DEBC, with C on the top right, B on the bottom right, E on the top left, and D on the bottom left. There is a vertical line from C to the base at A, where \(CA=6\) and \(BA=10\). There is also a right angle at E, where \(DE=6\) and \(DB=13\). The figure seems to have a few typos in the labels in the explanation part).

What is the area of the triangle BCD? (Diagram shows BCD on the base of a figure that looks like a Trapezoid DEBC, with C on the top right, B on the bottom right, E on the top left, and D on the bottom left. There is a vertical line from C to the base at A, where \(CA=6\) and \(BA=10\). There is also a right angle at E, where \(DE=6\) and \(DB=13\). The figure seems to have a few typos in the labels in the explanation part).
