The population of one type of fish, P1, and another type of fish, P2, are modeled by the equations P1 = 1000(3) a and P2
= 1000
1000(3)
where
r is the time in years.

Which expression describes the relationship between the population p1 and p2 in 3 years?

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
