How Do Different Dielectrics Affect Capacitance in a Parallel-Plate Capacitor?

[peaceinmideas]

Homework Statement

There is a parallel-plate capacitor with a plate area A = 5.52 cm2 and a plate separation d = 5.52 mm. The left half of the gap is filled with material of dielectric constant κ1 = 7.00; the right half is filled with material of dielectric constant κ2 = 15.0. What is the capacitance?

Homework Equations

C= K(epsil) A/ d

The Attempt at a Solution

I tried to add the two values of K, I also converted both A and d to m^2 and m, respectively. I got 9.74 x 10^-14 F

I'm getting a similar answer, except it disagrees in the 10^-14 part. I suspect the conversions to m^2 and m may be off; what did you get for A and d?
