If 'L' is the perimeter of a closed traverse, ΔD is the closing error, in departure, the correction for the departure of a traverse side of length l, according to Bowditch rule is
1
\(\Delta D \frac{l}{L}\)
2
\(\Delta D \frac{l^2}{L}\)
3
\(\Delta D \frac{L}{l^2}\)
4
\(L \times \frac{l}{\Delta D}\)
5
None of the above
