So we're gonna go from 2.9 to 3.1. So now we have an interval that actually has width, and so it'd be roughly the size of this yellow area that I'm shading in right over here. And we can approximate it with a rectangle, even though the top of this curve isn't flat, so we could say, look, it's approximately like a rectangle that is 0.2 high. And what's the width? The width here, if we're going from 2.9 to 3.1, the width is going to be 0.2 wide. And so we could approximate this area by approximating this rectangle, the area of the rectangle. 0.2 times 0.2, that would give us an area of 0.04.
