You are using an incorrect formula. This is why your answer is both numerically and dimensionally incorrect. The unit of electric field is not C/m2.
You have an infinite plane with a uniform surface charge density. The electric field at a point near such plane is given by a standard equation.
If you have covered Gauss' law in class, that equation should be in your lecture notes. Can you find that equation?
We cannot give direct answers here. All we can do is point out mistakes and provide hints.

This is the equation we deal with in Gauss's law. We didn't solve an example of this question, so I can't understand
