Answer:

1584 square kilometers.

Step-by-step explanation:

Here's the function I use.

[tex]y=a(1-r)^t[/tex]

a= starting amount

r= rate

t= years

First step: [tex]y=3700(1-0.055)^1^5[/tex]

Second step: [tex]=3700(0.945)^1^5[/tex]

Third step: =1583.72164269

Fourth step: Round to the nearest square kilometer. Since 1583.7 is closer to 1584, you must round up.

Fifth step: The final answer is [tex]1584 km^2[/tex]

Hope this helps and stay during these crucial times. We'll get through this!
