You have to divide the question into two parts.

First, use integration to find the area under OA.

The, find the area of the triangle.

Then add them to gether.

$\int_{0}^{2}x^3-8x^2+20x$

Then find the area of the triangle:

$\frac{1}{2}(x_b-x_a)y_a$

That comes to:

$\frac{1}{2}(\frac{10}{3}-2)16$

As $f(2)=16$

So when you add them together, you get $\frac{100}{3}$
