Answer:

15000N/m²

Explanation:

Given parameters:

Force exerted by the girl  = 450N

Area  = 300cm²

Unknown:

Pressure exerted by her feet  =?

Solution:

Pressure is the force per unit area on a body;

    Pressure  = [tex]\frac{force }{area}[/tex]

We need to convert the given area to m²;

        10000cm²   =  1m²

        300cm²  = [tex]\frac{300}{10000}[/tex]   = 0.03m²

Pressure = [tex]\frac{450}{0.03}[/tex]   = 15000N/m²
