"Bounded" means "enclosed". So, you have a region which is enclosed by the curve, the line y = 4 (horizontal line), the x-axis and the y-axis. This enclosed area is your shaded region.

Wait while I do this question. We integrate to y this time.

If you are not comfortable with this approach, there is also the usual approach of integrating with respect to x, but this will be longer. Let me know if you need those workings as well.
