MatroZZZ [7]

The number of Walmart Stores are there per 100,000 people is 1.43 stores

What does per 100,000 people mean?

It means the number of stores that could attend to 100,000 customers out of the total store number of 4,740

store per person=4,740/ 332,400,000

number of stores per person= 0.000014260

number of stores per 100,000 people=number of stores per person*100,000

number of stores per 100,000 people=0.000014260*100,000

number of stores per 100,000 people=1.43

What is the area of the following polygon?
muminat

The area of the polygon is 25.5 square units

<h3>How to determine the area of the polygon?</h3>

From the figure, we have the following coordinates

A = (-2, 1)

B = (3, 2)

C = (5, -3)

D = (-1, -3)

The area of the polygon is then calculated as:

A = 0.5 * |(x1y2 - x2y1) + (x2y3 - x3y2) + (x3y4 - x4y3) + (x4y1 - x1y4)|

Substitute the known values in the above equation

Area = 0.5 * |(-2 * 2 - 3 * 1) + (3 * -3  - 5 * 2) + (5 * -3  + 1 * -3) + (-1 * 1 + 2 * -3)|

Evaluate the sum of products

Area = 0.5 * |-51|

Remove the absolute bracket

Area = 0.5 * 51

Evaluate the product

Area = 25.5

Hence, the area of the polygon is 25.5 square units
