The figure shows the equipotential lines for another electric field. What is the approximate strength of the electric field at points A and B?

I used the equations:
Ex = -V/X
= -(25V-40V)/(0.005m-0m)
= 3000 V/m
Ey = -V/X
= ( 25V-40V)/(0.004m-0m)
= 3750 V/m
EA= sqrt (Ex squared + Ey squared)
= 4802 V/m
I'm not sure what else to do. Any pointers?
