    Answer:

    Pressure = 39200 N/m²

    Explanation:

    Given the following data;

    Mass = 60 kg

    Area = 150 cm²

    Conversion:

    1 centimeter square = 0.0001 meter square

    150 centimeter square = 150 * 0.0001 = 0.015 m²

    To find the pressure exerted on the ground by the person;

    Mathematically, pressure is given by the formula;

     Pressure = \frac {Force}{area}

    First of all, we would determine the force exerted by the person.

    Force = mass * acceleration due to gravity.

    We know that acceleration due to gravity is equal to 9.8 m/s².

    Substituting into the formula, we have;

    Force = 60 * 9.8

    Force = 588 Newton

    Next, find the pressure;

     Pressure = \frac {Force}{area}

    Substituting into the formula, we have;

     Pressure = \frac {588}{0.015}

    Pressure = 39200 N/m²
