### Hint:

Integration, as we all know, is the process of determining an area by first dividing it into a number of basic strips and then adding up each one. At this point, we can calculate the area enclosed by a curve and a line connecting a given set of points. Here we have given the curve  X- axis, x=1 and x=2. We have to find the area bounded by the given lines and curve.
