Question

3100 km^(2) Suppose that each year this area decrease by 3.25%. What will the area be after 11 years? Nearest square kilometer.

Answer 1

Explanation:

To calculate the area after 11 years with an annual decrease of 3.25%, we can use the formula:

New Area = Initial Area * (1 - Rate of Decrease)^Number of Years

Given that the initial area is 3100 km^(2) and the rate of decrease is 3.25%, we can substitute these values into the formula:

New Area = 3100 * (1 - 0.0325)^11

Calculating this expression, we find:

New Area ≈ 3100 * (0.9675)^11 ≈ 2457.17 km^(2)

Rounding to the nearest square kilometer, the area after 11 years will be approximately 2457 km^(2).
