A uniform slope was measured by the method of stepping. If the difference in level between two points is 1.8 m and the slope distance between them is 15 m, the error is approximately equal to
cumulative, + 0.11 m
compensating, ± 0.11 m
cumulative, - 0.11 m
none of these

We get Horizontal distance = 14.89 by Pythagoras formula & the error is cumulative.
So, 15 - 14.89 = 0.11.

Same doubt for me. How 1.08 =.11?

@Chandu.

How 1.08 =.11?

h2/21 = 1.8^2/(2*15) = 1.08~.11.

Slope correction = h^2/2L.
