Parallel plate capacitor – need to know overlap area

Parallel plate capacitor – need to know overlap area A student sets up two metal plates opposite to each other, as a **parallel plate capacitor**, with air as the dielectric between them. She knows the permittivity of air, and she measures the distance between the two plates. Before carrying out her experiment she wants to calculate the capacitance of this parallel plate capacitor, but she realises she needs to make another measurement first. What else does she need to measure?
