An engineer measures the force exerted perpendicular to a flat surface and the surface area of that surface.
Which calculation gives the pressure exerted on the surface?
force+area\text{force} + \text{area}force+area
force÷area\text{force} \div \text{area}force÷area
area÷force\text{area} \div \text{force}area÷force
force×area\text{force} \times \text{area}force×area
