Explanation:
The electric flux through the rectangle is given by
where
E is the electric field strength
A is the area of the rectange
is the angle between the direction of the electric field and of the vector normal to the plane of the rectangle
In this problem we have
E = 125 000 N/C
The area of the rectangle is
and the angle is
so, the electric flux is
