Answer
Area covered by forest in 11 years = 1092 km²
Explanation
When a quantity decreases at a constant rate, the value in some time is given as
A(t) = A₀ (1 - r)ᵗ
A(t) = Area of the forest in year t
A₀ = Original Area covered by forest = 2900 km²
r = Rate of decline = 8.5% = 0.085
t = Time = 11
A(t) = A₀ (1 - r)ᵗ
A = 2900 (1 - 0.085)¹¹
A = 2900 (0.915)¹¹
A = 2900 (0.3764)
A = 1092 km²
Hope this Helps!!!
