I don't know what R is, and I don't know what L is. I can assume that A is the area, but the equation your teacher gave you makes no sense to me, as the equation for a parallel plate capacitor is:

[tex]C=\frac{k\epsilon _0A}{d}[/tex]

For air or free space, k is about 1.

There's also another equation:

[tex]C=\frac{Q}{V}[/tex]

Distance of separation.
Area.
Capacitance
Voltage
[tex]\epsilon_0=8.85\times10^-12 \frac{C^2}{Nm^2}[/tex]
Q = charge

I can't say if the answer is right or wrong without you showing any work.
