Answer:
Scale factor: 2
Side of PR: 14
Side of PQ: 8
Explanation:
Divide the sides with the other given side to find the correct scale factor, side BC and side QR are what we will use, side QR being 12, we will divide the side by the other given side which is BC, 6 goes into 12 twice, so the scale factor is 2. Side PR is 14, and side AB is 8. All the original values are multiplied twice to find the larger triangles sides.
