So the value of the function is three. So this would be our second rectangle, our second division, I guess, used to approximate the area. And then last but not least, we would use the right boundary of this third subdivision when x equals 10, f of 10 is five. So just like that. And so then our right Riemann approximation using our right Riemann sum with three equal subdivisions to approximate the area, we would just add the area of these rectangles. So this first rectangle, let's see, it is three wide. And how high is it?
