@Samm.

A is the transverse cross-sectional area of vehicle and v is the velocity of the vehicle.
So wind resistance is directly proportional to A and square of velocity constant C is introduced to have a relationship between R, A and V.

C is the constant.

In case does not mention to take 1 value.
