Answer-
The area after 11 years will be 2225.28 km²
Solution-
This can be represented as exponential decreasing function,
[tex]y=a(1 - r)^t[/tex]
Where,
Putting the values,
[tex]y=4800(1-0.0675)^{11}[/tex]
[tex]\ =4800(0.9325)^{11}[/tex]
[tex]\ =4800\times 0.4636[/tex]
[tex]\ =2225.28[/tex]
Therefore, at this rate the area of the forest after 11 years will be 2225.28 km².
