In the triangle $P Q R$, the lengths of $P T$ and $T R$ are in the ratio of $3:2$.
$ST$ is parallel to $QR$. Two semicircles are drawn with PS and PQ as diameters, as shown in the figure.
Which one of the following statements is true about the shaded area $PQS$?
Note: The figure shown is representative.

- The shaded area is $\frac{16}{9}$ times the area of the semicircle with the diameter PS.
- The shaded area is equal to the area of the semicircle with the diameter PS.
- The shaded area is $\frac{14}{9}$ times the area of the semicircle with the diameter PS.
- The shaded area is $\frac{14}{25}$ times the area of the semicircle with the diameter PQ.
