Answer 2

Answer:

6 cm

Step-by-step explanation:

Here, PQ || BC and P is the mid point of AB

so, Q is the mid point of AC

Again, PR || AC and P is the mid point of AB

so, R is the mid point of BC

If a line be parallel to a side of a triangle and through the midpoints of others side the length of the seg be half of its parallel line.

so, QR=1/2* AB= 1/2*12=6
