Answer»

Answer:

Triangle PQR circumscribes of radius 8 CM take center of circle as O

join PO,QO,RO and OD,OE,OT

D and E are points on PQ and PR

ar of triangle POQ+ar tri. QOR+ar tri. POR=336

take HEIGHT as 8 cm,PQ=14+a,PR=16+a,QR=14+16=30

find value of a

Solve the eqn formed answer −PQ=12+14=26

PR=12+16=28
