Its 10 cm because 15/9 on one side is 1.6666666 or 5/3 that will have to be your scale factor from going from small to big. So 6 time 5/3 will get you 10.

ANSWER

The measure of side PR is

10 \: cm


Step-by-step explanation

Since the two triangles are similar, the ratio of corresponding sides are proportional.


This implies that,


(|QR|)/(|KL|) = (|PR|)/(|JL|)




We now substitute the values of the corresponding sides to obtain,


(15)/(9) = (|PR|)/(6)



We multiply both sides if the equation by 6 to obtain,



(15)/(9) * 6= |PR|


We simplify further to obtain,


(15)/(3) * 2= |PR|





5 * 2= |PR|



|PR| = 10 \: cm
