Answer:2117km2

After 1 year: 3800 km² - (8.5% of 3800 km²) = 3473 km² (rounded to the nearest square kilometer) After 2 years: 3473 km² - (8.5% of 3473 km²) = 3180 km² (rounded to the nearest square kilometer) After 3 years: 3180 km² - (8.5% of 3180 km²) = 2910 km² (rounded to the nearest square kilometer) After 4 years: 2910 km² - (8.5% of 2910 km²) = 2661 km² (rounded to the nearest square kilometer) After 5 years: 2661 km² - (8.5% of 2661 km²) = 2431 km² (rounded to the nearest square kilometer) After 6 years: 2431 km² - (8.5% of 2431 km²) = 2221 km² (rounded to the nearest square kilometer) After 7 years: 2221 km² - (8.5% of 2221 km²) = 2029 km² (rounded to the nearest square kilometer) So, after 7 years, the area of the forest will be approximately 2029 km².
