Step-by-step explanation:
Hello,
<em>I would recommend that you checked the answers I have already provided as this is the same method for all these questions, and maybe try to solve this one before you check the solution.</em>
<u>At the beginning the area is 2100</u>
<u>After one year</u> the area will be
2100*(1-3.5%)=2100*0.965
<u>After n years</u> the area will be

So after 5 years the area will be

So rounded to the nearest square kilometer is 1757
Hope this helps
