Question

A map of the Orchid Hill Neighborhood is shown. The population of Orchid Hill Neighborhood is 360 people.

Answer 1

Answer:

(a) The area is 0.03 square miles

(b) The population density is 12000 people per square miles

Step-by-step explanation:

Given

See attachment for complete question

Solving (a): Area of Orchid Hill (in square miles)

The dimension of the neighborhood is 4 blocks by 3 blocks

Since each block are of the same dimensions

The area is calculated as:

$Area = 4blocks * 3 blocks$

If $20\ blocks = 1\ mile$ then:

$1\ block = \frac{1}{20} mile$

$1\ block = 0.05mile$

So, we have:

$Area = 4blocks * 3 blocks$

$Area = 4 * 0.05 * 3 * 0.05$

$Area = 0.03mi^2$

Solving (b): The population density of the neighborhood as people per square mile

From the question, we have:

$People = 360$

$Area = 0.03mi^2$ --- calculated

So, the population density is:

$Density = \frac{People}{Density}$

$Density = \frac{360}{0.03}$

$Density = 12000$
