Close Traverse leg length = 20525m.
L = +5.080m.
D = -51.406m.
Total error(E)= √ L^2+D^2.
ANS = 51.65.
RELATIVE PRECESSION = E÷TRAVERSE LEG LENGTH.
ANS=(51.65÷20525)= 1:397 = 1:400(APPROX).
L = +5.080m.
D = -51.406m.
Total error(E)= √ L^2+D^2.
ANS = 51.65.
RELATIVE PRECESSION = E÷TRAVERSE LEG LENGTH.
ANS=(51.65÷20525)= 1:397 = 1:400(APPROX).

Ans is A.
Error/perimeter
Error = √(L^2 + D^2) = 51.6564,
Perimeter = 20525.
So the answer is 1:397 ~ 1:400.
Error/perimeter
Error = √(L^2 + D^2) = 51.6564,
Perimeter = 20525.
So the answer is 1:397 ~ 1:400.
