Methods of Surveying

Surveying is the practice to determine the relative three-dimensional positions of various points on the earth’s surface. This is done by computing the vertical and horizontal distances, angles between the points, collecting the observations, and plotting them on a map of any appropriate scale. Accuracy can be achieved by using the latest instruments like a theodolite, tachometer, etc. Leveling is a subdivision of surveying where the objective is to locate the elevation of objects considering a datum level.

Question

A surveyor starting from a point A moves N. 34°52' E. a distance of 606' 2.5" to
point B. Next, she moves N. 57°58' E. a distance of 379' 8.75" to point C. Next,
she walks S. 4°28' W. a distance of 1656' 11.75" to point D. Finally, she returns to
the starting point.
What distance must she walk to return to the starting point? (Answer accurate to
the nearest quarter inch.)
feet &
inches
What heading does she walk from the fourth point to return to the starting point?
(Answer accurate to the nearest minute.)

W.
What is the acreage of this plot of land?
area =
acre
Your answer should be accurate to 3 decimal places.
Notes:
* the prime symbol in an angle represents minutes: 60' = 1°
