Answer:

3.32 units

Step-by-step explanation:

From the given figure, applying ratios of similar triangles:


\begin{gathered} (QT)/(RT)=(RT)/(TS) \\ \implies RT^2=QT* TS \end{gathered}

Substitute the given values:


\begin{gathered} RT^2=5*2.2 \\ RT^2=11 \\ √(RT^2)=√(11) \\ RT=3.32\text{ units} \end{gathered}

The length of RT is 3.32 units (to the nearest hundredth).
