A displacement vector from a charge to a field point is r→=(12i^−5j^)\(\overrightarrow{r}\)=\(\left\)(12\(\hat{i}\)-5\(\hat{j}\)\(\right\)) cm\(\text{cm}\) . What is the corresponding scalar distance rr in SI units?

A displacement vector from a charge to a field point is $\vec{r} = (12 \hat{i} - 5 \hat{j})$ $cm$ . What is the corresponding scalar distance $r$ in SI units?
