Giraffes are most well-known to dwell in the land of Africa. According to a scientific research and reliable sources, the population of giraffe in said location had dropped by 40% from its count of 140,000 from 15 years ago. 

(a) This gives us the population of the giraffes only 84,000.

(b) The population density is equal to the number of giraffes sharing the same area. Hence, from the given data, the answer would have to be 16 giraffes/km².

Answer:

The size of the giraffe population is 16

The population density is [tex]16\frac{giraffes}{km^{2}}[/tex]

Explanation:

To solve this exerciste we first need to make two definitions.

The population of a particular species found at a certain location is the number of individuals. In this case, in the African savanna on that square kilometer the population is 16 giraffes.

We also define population density as the count of number of individuals per unit of area.

[tex]PopulationDensity=\frac{Individuals}{area}[/tex]

In this case, we have 16 giraffes on a square kilometer ⇒

Population density = [tex]16\frac{giraffes}{km^{2}}[/tex]
