For a given traverse, the sum of latitudes was found to be 1.89 and the departures of the sides were calculated to be -1.17. What is the closing error of the given traverse?

1.491 ft
2.223 ft
3.060 ft
None of the above

Explanation

Answer: B - The closing error of the given traverse is 2.223 ft.

Solution

Use the closing error formula e = [ΣL² +ΣD²]^½
Where L = latitude = 1.89

D = departure = -1.17

E = [(1.89)² +(-1.17)²]^½

= [3.572 +1.369]^½ = 2.223ft
