(a) Describe, with the aid of a suitable diagram, an open traverse

(b) A compass traverse round a school compound produced the following field record: 

Line	Length (mm)	Bearing
AB	370	260º
BC	450	198°
CD	265	110°
DE	560	35°
EA	140	330°

Use the data above to:
(i) plot the area of the compound on a scale of 1cm to 50m
(ii) find the direct distance between D and A, in metres.
