C. 28 square units
To find the area of the rectangle within the composite shape, you need to subtract the area of the triangle from the total area of the composite shape.
Total area = 40 square units
Area of triangle = 1/2 * base * height = 1/2 * 4 * 6 = 12 square units
Area of rectangle = Total area - Area of triangle = 40 - 12 = 28 square units
Therefore, the area of the rectangle within the composite shape is 28 square units.
