Answer:
The population density for the village and the estate together is 112.5 people per square kilometer.
Step-by-step explanation:
The statement is incorrectly written. Correct form is described below:
<em>A village has an area of 6 square kilometers and a population density of 600 people per square kilometer. An estate stituated next to the village has a population of 800 and a population density of 400 people per square kilometer. Work out the population density, in people per square kilometer, for the village and the state together. </em>
Dimensionally speaking, the population density of the village and the estate together (
), measured in people per square kilometer, is defined by this expression:
(1)
Where:
,
- Population of the village and the estate, measured in people.
,
- Area of the village and the estate, measured in square kilometers.
First, we find the population of the village:


Then, we determine the area of the estate:


If we know that
,
,
and
, then the population density of the village and the estate together is:


The population density for the village and the estate together is 112.5 people per square kilometer.
