    Answer:

    1 m²

    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
