Answer: the population will be 22234 after 11 years.

Explanation:

The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 13000

r = 5% = 5/100 = 0.05

t = 11 years

Therefore,

A = 13000(1 + 0.05)^11

A = 13000(1.05)^11

A = 22234 to the nearest whole number.
