Following are the perpendicular offsets that were taken from a chain survey: Change (m) 30 60 90 120 150 180 210 Offset length (m) 8.76 7.89 9.43 8.44 7.54 7.35 8.75 The area enclosed by the chain line and irregular boundary by Trapezoidal rule is m2.

FUNDAMENTALS OF SURVEYING 1 All azimuths are measured from South. All angles must be written to the nearest minute only. All latitudes and departures must be written to two decimal places only. 3.The algebraic sum of latitude and departure of a six-sided tract of land are as follows: EL = - 1.35m, precision or relative error of the survey. ED = + 1.18 m. If the total length of boundary is 455. 56m, determine the 4.The latitude and departure of a traverse line were computed as +77.56m and – 87.78m respectively. a) Determine its bearing b) Determine azimuth, c) Determine is distance.
