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
