The horizontal ground lengths of a four-sided closed polygon traverse were measured as follows: AB = 479.549 m, BC = 830.616 m, CD = 685.983 m and DA = 859.689 m. If the average orthometric height of the area is 1250 m, the geoidal separation is −30.0 m, and the scale factor for the traverse 0.9999574, calculate grid lengths of the lines for use in computing SPCS83 coordinates. (Use 6,371,000 m for an average radius of the Earth.)
