So what do we think this, what do we think, what do we think this area, this area right over here is going to be? And we already know how we can denote it. That area right over there is equal to the definite integral from a to b of the function we're integrating is c f of x dx. I guess to make the question a little bit clearer, how does this relate to this? How does this green area relate to this yellow area? Well, one way to think about it is we just scaled the vertical dimension up by c. So one way that you could reason it is, well, if I'm finding the area of something, if I have the area of a rectangle, and I have the vertical dimension is, let's say the vertical dimension is, I don't want to use those same letters over and over again. Well, I'll just, well, let's say the vertical dimension is alpha and the horizontal dimension is beta.
