In triangle \( A B C \), if \( P, Q, R \) divides sides \( B C, A C \), and \( A B \), respectively, in the raito \( k: 1 \) (in order). If the ratio
\( \mathrm{P} \) \( \left(\frac{\text { area } \triangle P Q R}{\text { area } \triangle A B C}\right) \) is \( \frac{1}{3} \), then \( k \) is equal to
