    Answer:

    4.99 * 10^8 Nm²

    Explanation:

    Given that:

    Dimension of football field = 9000 cm by 5500 cm

    Area of field = lengtb * width

    Area of field = 9000cm * 5500 cm

    Area of field = 49500000 cm²

    Converting the area to m²

    49500000 cm² in m² equals :

    49500000 / 10000 = 4950 m²

    Pressure = Force / Area

    Atmospheric Pressure = 101 Kpa = 101 * 10^3 Pa

    Force = pressure * Area

    Force = (101 * 10^3) * 4950 m²

    Force = 4.99 * 10^8 Nm²
