P=2(L+W)
first one
P=2(6+4)
P=2(10)=20
doubled
12 and 8
P=2(12+8)
P=2(20)
P=40
the change is i20
percent change=change/original
change/original=20/20=1=100%
100% change

Answer:
For 15 years - 
After 15 years - 
Step-by-step explanation:
We have that,
Initial population is 110,000 which grows by the rate 4% i.e. 0.04 for 15 years.
Since, the exponential growth is given by
,
where P is the initial population, r is the rate of interest and x is the number of years.
Thus, the required population is
i.e.
.
Moreover, after 15 years i.e. x+15 years, the population will be
.
Thus, the population after 15 years is
.
