A forest is enclosed by four straight boundaries AB, BC, CD and DA. Point B is 25km on a bearing of 315° from A, C is directly south of B on a bearing of 260° from A and D is 30km on a bearing of 210° from C.
- Using a scale of 1:500,000, represent the above information on a scale drawing
- Using the scale drawing, determine the:
- distance, in kilometres, of D from A:
- bearing of A from D
- Calculate the area, correct to 1 decimal place, of the forest in square kilometres.
