In a triangle ABC, P and Q are points on AB and AC, respectively, such that AP=1cm, PB=3cm, AQ=1.5cm and CQ=4.5 and PQ|| BC . If the area of triangle APQ is 12 cm^2 , then find the area BPQC. एक त्रिभुज ABC में, P और Q क्रमशः AB और AC पर बिंदु हैं, जैसे कि AP = 1cm, PB = 3cm, AQ = 1.5cm और CQ = 4.5। यदि triangle APQ का क्षेत्रफल 12 cm^2 है, तो BPQC क्षेत्रफल ज्ञात करे
