Some book answered it 1.5a^2/100.
How it's come please explain?

ch= s(1-cosθ)
ch= s- s cosθ
ch= s - d
Because d= s. cosθ.
For example: s=100, slope angle 45 degree
d= 100 . 0.70710
d= 70.71 THIS IS THE CORRECTION OF SLOPE LENGTH.
ch= 100-70.71.
ch= 29.29.
Ch is the correction of measured slope distance due to slope;
d is the horizontal distance.
ch= s- s cosθ
ch= s - d
Because d= s. cosθ.
For example: s=100, slope angle 45 degree
d= 100 . 0.70710
d= 70.71 THIS IS THE CORRECTION OF SLOPE LENGTH.
ch= 100-70.71.
ch= 29.29.
Ch is the correction of measured slope distance due to slope;
d is the horizontal distance.

100a^2÷2 = 50a^2.

I agree on @Garry and @Deepa.
It should be 50a^2.
It should be 50a^2.

Agree @ Deepa.
The answer should be 50 a^2.
The answer should be 50 a^2.

@Md Shekhar.
Then it will be 50a^2, right?

Slope correction=h^2/2L;
where h=L*angle in radian(a),
Here L=100 links,
So, slope correction=100*a^2.
where h=L*angle in radian(a),
Here L=100 links,
So, slope correction=100*a^2.

Correction is = 100(sec a-1).
