So in order to show what is consumer surplus in the figure, we will highlight the region between point C, B and A.
The use of the graphical explanation when it comes to understanding what is consumer surplus is highly important because sometimes, we are not supposed to work with numerical figures. In such a case, we are supposed to show the concepts through graphical explanations. Though it is extremely easy to calculate what is consumer surplus when numerical values are given but the catch is to fully understand and grasp the graphical concepts.
