Electric Field: not quite getting the correct answer

[Seraph404]

Homework Statement

E1 = 2.9E4 N/C
E2 = 8.6E4 N/C
Both fields are uniform

Homework Equations

flux = $$\int$$ E_perp*dA = Q_encl/ $$\epsilon$$₀

The Attempt at a Solution

flux1 = E1cos(30)(.05m)(.06m)
flux2=E2cos(30)(.05m)(.06m)
(flux1+flux2) = Qencl/ $$\epsilon$$₀

Homework Statement

But my answer is wrong. I appreciate any help.

What is the question?

Also, those fields are at an angle of 60 degrees from the surface normal.
