7 weeks X 7 days in a week = 49 days.
3 trees on each truck X 50 trucks = 150 trees.
3 trees on each truck X 100 trucks = 300 trees.
Therefore, 150 - 300 trees are carried off each day.
150 trees X 49 days = 7350 trees are carried off in 7 weeks.
300 trees X 49 days = 14700 trees are carried off in 7 weeks.
Since there are 300 - 400 trees per hectare:
7350 divided by 300 = 24.50 hectares
14700 divided by 400 = 36.75 hectares
After 7 weeks, 24.5 - 36.75 hectares of trees have been cut illegally.
