A windbreak, 15 m in height and 200 m in length, is established to protect the land from wind erosion in an arid area. The minimum wind velocity at the height of 15 m above the ground required to move the most erodible soil fraction is 9.6 m s⁻¹. If a year during period wind velocity at 15 m height is 16 m s⁻¹ and the wind direction deviates 40° from the line perpendicular to the windbreak, the area protected by the windbreak in ha is [round off to 2 decimal places]
