Answer: the area be after 12 years is 3002 km^2
Explanation:
We would apply the formula for calculating exponential decay. It is expressed as
A = b(1 - r)^t
where
A is the area after time t
b is the initial area r is the area
t is the time taken
From the information given,
b = 4400
r = 3.75% = 3.75/100 = 0.0375
t = 12
By substituting these values into the formula,
A = 4400(1 - 0.0375)^12
A = 4400(0.9625)^12
A =
the area be after 12 years is 3002 km^2
