AB=2x units and BC=x units.
If point D divides the segment AB in the ratio 3:2, then
AD=3y units and DB=2y units.
Since AD+DB=AB, then

Answer:
time period is 260.57 years
Step-by-step explanation:
given data
growth rate = 3.4 % = 0.034
population = 4118000
area P = 29000000000 square yard
to find out
time period that one person for every square yard of land need
solution
we will apply here population growth formula that is
total population P = initial population × ..............1
here r is rate of growth and t is time period and
we consider here initial population is current population
so put value in equation 1 to get t
29000000000 = 4118000 ×
take ln both side
ln 7042.25 = ln
8.8596 = 0.034 t
t = 260.57
so time period is 260.57 years
