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:)

so

230/7 = pressure = 32.86 N/m^2

32.86 * area = 6500

solve for area
