20. Given an ellipse $C$: $\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1 \left( a > b > 0 \right)$ passes through point $M\left( 1,\frac{3}{2} \right)$, $F_1$ and $F_2$ are the two foci of ellipse $C$, and $\left| MF_1 \right|+\left| MF_2 \right|=4$, $O$ is the center of ellipse $C$.

(1) Find the equation of ellipse $C$;

(2) Suppose $P,Q$ are two different points on ellipse $C$, and $O$ is the centroid of $\Delta MPQ$, find the area of $\Delta MPQ$.
