Hello!

The definition of a pressure is a force over an area, or more precisely the quotient of a force acting perpendicularly to a flat surface, to the area of that surface:

P = F/A.

The unit of a pressure is Newton divided by meter squared, `N/m^2.` It is called Pascal and is denoted as Pa. So it is simple to find an area when the pressure in Pa and the force in N are given:

A = F/P.

In our case it is equal to 100 N / 500 Pa = **0.2** `m^2.` This is the answer.

Blaise Pascal (1623 – 1662) is a famous physicist, mathematician and philosopher who discovered among other things Pascal's Law (or principle) of transmission of fluid-pressure. The principle states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid.
