Question

Evaluate both sides of the Stokes theorem for the field:
H = 6xy ax + 3y2 ay

and the rectangular path around the region:
2 <= x <= 5, -1 < y < 5, z = 0

positive direction of dS is az

ans=-126 A,-126A

Assume dS = dS az
I can't find the correct answer

StokesTheorem:


I am getting different values for both sides of the theorem. theorem.
