a. i. Calculate the area of the complete semicircunference, and substract the area of both internal semicircunference.
Let A the area that we need to calculate, let B the area of the total semicircunference, and C the sum of the internal semicircunferences.

a. ii. The same idea. Let P the perimeter that we need to calculate, and let P' the perimeter of the total semicircunference, and Q the sum of the perimeters of the internal semicircunferences.

b. i 
b. ii 
Answer: there would be 25004 after 7 years.
Step-by-step explanation:
The population of rabbits in increasing by 15% each year. This means that 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 = 9400
r = 15% = 15/100 = 0.15
t = 7
Therefore,
A = 9400(1 + 0.15)^ 7
A = 9400(1.15)^ 7
A = 25004
B is the right answer !!!!!!
