Three towns P, Q and R are such that P is on a bearing of 120° and 20km from Q. Town R is on a bearing of 220° and 12km from P hence a)Using a scale of 1cm to2km, draw and locate the positions of the three towns. b) Measure: i) the distance between Q and R in Kilometres. ii) the bearing of P from R. iii) the bearing of R from Q. c) Calculate the area of the figure bounded by PQR.​
