6. Determine the perimeter of the similar triangles

If \(\triangle ABC \sim \triangle PQR\), \(BC =\) 26 \(cm\) and \(QR =\) 34 \(cm\) and perimeter of \(\triangle PQR =\) 93 \(cm\), then the perimeter of \(\triangle ABC\) is  \(cm\).

 

(Note: If the answer is a whole number, write as it is. If not, round off the number to \(2\) decimal places.)
