Question

a certain forest covers an area of 4400 KM2 to supposed to each year this area decreases by 7.5% what will be the area after 11 years

Answer 1

To calculate the area of the forest after 11 years, we need to apply the 7.5% decrease to the initial area for each year.

Given:

Initial area of the forest = 4400 km^2

Decrease rate = 7.5% = 0.075

To find the area after 11 years, we can use the formula:

Area after 11 years = Initial area * (1 - Decrease rate)^11

Substituting the given values:

Area after 11 years = 4400 km^2 * (1 - 0.075)^11

Calculating the result:

Area after 11 years ≈ 4400 km^2 * (0.925)^11

≈ 4400 km^2 * 0.417555646

≈ 1835.437 km^2

Therefore, the area of the forest after 11 years will be approximately 1835.437 km^2.
