Physics Help, Will give best answer!?

Question

What is the average pressure on the soles of the feet of a standing 89-kg person due to the contact force with the floor? Each foot has a surface area of 0.021 m2.

This has been on here before but the answer was not working for me. If you could help me out that would be great.

Also, the answer is expressed in kPa.

Answer 1

P=mg/(2A)
P = 89 x 9.81/(2 x 0.021 )=
P=20800 M/m^2 or 20,800 Pascals

so is

20.8 kPA
