A series of offsets were taken at 10 m. intervals from a survey line to an irregular boundary line: 0.0, 3.25, 4.10, 6.45, 8.90, 5.75, 8.50, 0.0 m. Calculate the area enclosed between the survey line and the boundary line by using the _TRAPEZOIDAL METHOD_ Read more

A chaining party measures a distance AB along a slope with a 100 m. tape which is known to be too long by 0.04 m. The distance from A at the base of the slope to B at the summit is recorded as 416.85 m. Levels run from A to B establish a difference in elevation of 22.50 m. What ... Read more
