The town of Manchester (population 50,000) has the shape of a rectangle that is 5 miles wide and 7 miles long.
topjm [15]

Answer:

Step-by-step explanation:

Population density is expressed as the ratio of the total number of people, N living in or occupying an area or space to the total area or space. Therefore

Population density = number of people/area

A) The town of Manchester (population 50,000) has the shape of a rectangle that is 5 miles wide and 7 miles long. The area would be

5 × 7 = 35 square miles

Population density = 50000/35

= 1429 people/square mile

B) The business area has radius of 1 mile. Its area would be

πr² = 3.14 × 1² = 3.14 square miles.

The area where people reside outside the business area is

35 - 3.14 = 31.86 square miles

Population density = 50000/31.86

= 1569 people per square mile

What is the perimeter of a square abcd if a(0,0 and b(0,5?
Ghella [55]
So squares have 4 congruent sides. When you plot the points (0,0) and (0,5) the side length is 5 units. We can then take 5+5+5+5 and know the perimeter is 20 units.
