The area of the rectangle can be calculated by subtracting the area of the two triangles from the total area of the composite shape.
Since the two triangles have a combined area of 2 * (1/2 * 4 * 3) = 2 * 6 = 12 square inches, the area of the rectangle is 40 - 12 = 28 square inches.
Therefore, the area of the rectangle within the composite shape is 28 square inches.
