For slope (M) up to 20%.
Slope correction(Sc) = h^2/(2l).
Here d = 20m,
M = h/d,
0.2 = h/20.
H = 0.2 * 20 = 4m.
Here the nearest one is 3m.
So 3m is the appropriate answer.

l = 20 m.
H2 = 2l,
H2 = 2*20,
H2 = 40.
And;
H = 6.32 or 6.33,
√40 = 6.32.
H2 = 2l,
H2 = 2*20,
H2 = 40.
And;
H = 6.32 or 6.33,
√40 = 6.32.

Second term will be neglected when h=3cm not 3meter for length 20 meter.

According to me, the solution is;
Slope correction(Sc) = h^2/(2l).
Here d = 20m,
M = h/d,
0.2 = h/20.
H = 0.2 * 20 = 4m.
