After a quick sketch of the problem, one can deduce that there are $3$ rectangles in the figure, each with side length $6$ and width $3$. Therefore, the combined areas of the rectangles is $54$. The other three regions are circle-shaped areas, probably expressed in some form of $\pi$. Answer choices $(\mathrm{A})$, $(\mathrm{D})$, $(\mathrm{E})$ are impossible because they either lack an integer or $\pi$ in the answer, and $(\mathrm{C})$ is impossible since $18\sqrt{3}$ clearly does not belong to the rectangle or the circular areas. We can conclude that the only choice left is $\boxed{54+9\pi }$.
