AI Drawing Prompt Reference

Draw a trapezium and calculate its area. Start by taking point C on a line, then draw a circle centered at C with radius b, and find the intersection D with the line. Next, connect points A, C, D, and B to form the trapezium. Then, connect points A, C, and B, and points C, D, and B to form two triangles. Finally, take a point inside each triangle for area calculation.
