The length of PR is 16 inches.
Solution:
PQR is a triangle and ST is the mid-segment of ΔPQR.
Given ST = 8 inches
By triangle mid-segment theorem,
<em>The segment connecting the mid-points of two sides of a triangle is parallel to the third side and is half of the length of that side.</em>



Multiply by 2 on both sides.

⇒ 16 = PR
The length of PR is 16 inches.
