A certain forest covers an area of [tex]3700 \, \text{km}^2[/tex]. Suppose that each year this area decreases by 4%. What will the area be after 14 years?

Use the calculator provided and round your answer to the nearest square kilometer.

Answer :

Final answer:

The area of the forest will be approximately 2100 km^2 after 14 years, computed using the exponential decay formula.

Explanation:

The given problem is a classic example of a decrementing percentage over time. Since the area of the forest is decreasing by 4% annually, we can treat this is as an exponential decay problem. We use the exponential decay formula, A = P(1 - r)^n, where A is the final amount (the area of the forest after 14 years), P is the principal amount (the initial area of the forest), r is the rate of decrease per period (4% per year, expressed as 0.04), and n is the number of periods (14 years).

By substituting the given values into the formula, we calculate A = 3700 * (1 - 0.04)^14. After performing the calculation, the resulting area of the forest after 14 years is approximately 2100 km^2.
