We know that

• The mass is 59 kg.

,

• The area is 16 cm^2.

The formula of pressure is


P=(F)/(A)

Where F refers to the weight of the person, W = mg. The acceleration of gravity is 9.81 m/s^2.


P=(mg)/(A)=\frac{59\operatorname{kg}\cdot9.81((m)/(s^2))}{0.0016m^2}

Note that 16 cm^2 = 0.0016 m^2.


P\approx361,743.75Pa

Therefore, the pressure exerted on the floor is 361,743.75 Pa.
