Answer:

The equation which represent the area of forest creases each year is 2000 km²
(0.94)^(12) and

The area is 952 km² .

Explanation:

Given as :

The rate of depreciation of forest area each year = r = 6%

The initial area of forest = i = 2000 square kilometers

Let The final area of forest = f = x square kilometers

The time period for depreciation = 12 year

Now, According to question

The final area of forest = The initial area of forest ×
(1-(\textrm rate)/(100))^(\textrm time)

Or, f = i ×
(1-(\textrm r)/(100))^(\textrm 12)

Or, f = 2000 km² ×
(1-(\textrm 6)/(100))^(\textrm 12)

Or, f = 2000 km² ×
(0.94)^(12)

∴ f = 2000 km² × 0.475920

I.e f = 951.84 ≈ 952 km²

So, The equation which represent the area of forest creases each year = f = 952 km²

Hence,The equation which represent the area of forest creases each year is 2000 km²
(0.94)^(12) and the area is 952 km² . Answer
