Question

A Seven-sided closed field traverse has the following angles and distances in meters which were measured using a Total station:

AB = 51.7660;

BC = 76.9470;

CD = 37.0700;

The adjusted angles are as follows:

A = 128˚27’02”;

B = 101˚41’49”;

C = 102˚22’05”;

D = 143˚12’43”;

E = 161˚08’23”;

F = 131˚57’22”;

G = 131˚10’35”;

DE = 29.2019;

EF = 28.7758;

FG = 36.7056;

GA = 41.9555;

azimuth AB =251˚00’00''

question

1. Compute the coordinates of the traverse stations using coordinates of station A as 1,000.000 N, 1,000.000 E.
2. Compute the area enclosed by the traverse using the co-ordinate method.
3. It was decided to divide the traverse into two parts AGFED and DCBA, find the area of each part and the length and direction of AD.
