what formula do i need in order to solve this

a force of 230 N applied on a hydraulic lift raises an automobile weighing 6500 N. If the applied force is exerted on a 7.0 m^2 piston, what is the area of the piston beneath the automobile?

can someone show me how to do this in steps or tell me what formula to use

thanks:)
