Calculate the area: From a point A, proceed east for 300 m to Point B. Then travel 420 m on a bearing S35°E to point C. Then travel along a bearing of S40°W for 500 m to Point D. Then return to Point A.

Answer 1

X = 300 + 420*cos305 + 500*cos230=220 m.
Y = 420*sin305 + 500*sin230 = -727 m.

Area = X * Y = 220 * 727 = 159,940 m^2.
