14. An ellipse with a major axis of length 6 inches and a minor axis of length 4 inches is inscribed in a rectangle, as shown below. The region inside the rectangle but outside the ellipse is shaded. What is the area, in square inches, of the shaded region?

(Note: The area, A, of any ellipse can be found by the formula A = πab where a is the length of the major axis and b is the length of the minor axis.)
