Answer:
i) Find BC
∵ P is midpoint of AB
∵ R is midpoint of AC
∴ PR || BC
∴ BC = 2* PR
BC = 2* 5
BC = 10cm
ii) Find CA
∵ P is midpoint of AB
∵ Q is midpoint of BC
∴ PQ || CA
∴ CA = 2* PQ
CA = 2* 4.8
CA = 9.6cm
iii) Find QR
∵ Q is midpoint of BC
∵ R is midpoint of AC
∴ QR || AB
∴ QR = 1/2 AM
QR = 1/2 8.4
QR = 4.2 cm
