Answer:
1 m²
Step-by-step explanation:
Applying,
P = F/A.................. Equation 1
Where P = Pressure, F = Force, A = Area
Make A the subject of the equation
A = F/P............... Equation 2
From the question,
Given: F = 400 N, P = 400 N/m²
Substitute these values into equation 2
A = 400/400
A = 1 m²
Hence the area of the person is 1 m²
