Look at the points of intersection
#integration areas

So the base is 3 simply because that’s where the x coordinate goes up to ( in this case from 0 to 3) meaning integrate between 0 and 3
It’s not
So they integrated between 0 and 3 for the whole curve
Which is the 9
And the area under the triangle is 0.5bh
Well area of the triangle

Because if you do the integral - the area of triangle, you get the area of the shaded region.

And to find the top part they need to subtract the area of the curve from the area bounded by the triangle
And that gives the top part
You are finding the area between 0 and 3

There are bounds
amber compass
Not the entire entire curve
amber compass
There are bounds
Exactly
If you were asked to find the area of the whole curve you wouldn’t have the limits
Yeah
