Answer:
there is 6500 females
there is 4875 males
and there is 1625 more females than males
a. 27
b. 3
c. 15
d. 22
First we need to find the length. So we do 126/3 to get 42. The length is 42. Now to find perimeter we do 2(42)+2(3) or 42+42+3+3.
Both ways are right ways. The perimeter is 90 meters.
Hope that helps!!
