Explanation:
To explain this problem, we need to broach over the concept of pressure.
Pressure is the force applied per unit area on a body.
Pressure =
We see that the higher the force, the higher the pressure applied. Pressure is directly proportional to force.
Area shares an inverse relationship with pressure. The higher the pressure the lower the area and vice versa.
A high-heeled show shoe has a very small surface area compared to the surface of snowshoes which are larger.
