**Answer:**

**The area of forest after 8 years , decreases at the rate of 7.25% is 2081.108 square kilometers .**

**Step-by-step explanation:**

Given as :

The initial area of forest = 3800 square kilometer

The rate of decrease of area every year = r = 7.25 %

The time period for its decrease = t = 8 years

Let The forest area after 8 years = A square kilometers

Now, According to question

**The forest area after 8 years = Initial area of forest × **

or, The forest area after 8 years = 3800 km² ×

or, The forest area after 8 years = 3800 km² ×

Or, The forest area after 8 years = 3800 km² ×

Or, The forest area after 8 years = 3800 km² × 0.54766

Or, The forest area after 8 years = 2081.108 km²

So, Area of forest after 8 years = 2081.108 km²

**Hence The area of forest after 8 years , decreases at the rate of 7.25% is 2081.108 square kilometers . Answer**
