Question
Calculate the area bounded by the curve y=16/x^2, the line x=4 and the line y=16.

I know how to do this question without the x=4. What do I do with the x=4?

Answer
I have provided a diagram for you to see things in a clearer manner:





The area of the shaded region is the question's request.

You can consider using the area of a rectangular block (bolded in green) and subtract the area under the curve (between x=1 and x=4) from it to get your answer.
