I have solved a problem, and my answer differ from the one in the book from where it's taken. I think I did it correctly, can you assist ?

In the attached photo we have the graph of f(x)=0.5x^2

(half of x squared)

In the rectangle ABCO, BC is twice the size of OC. Calculate the dashed area.

The answer in the book is 21.3333

My answer is 10.666667

I think that 21.3333 is the area that complete to the whole rectangle. Am I right ?

Thanks !
