Question

You are standing amongst a crowd for a parade that is 10 feet deep, on both sides of the street, and 1 mile long. If each person occupies 2 square feet, estimate the number of people watching the parade.
52,800 people
26,400 people
13,200 people
200 people

Answer 1

Answer:

The number of people watching the parade is 26,400

Step-by-step explanation:

Breadth of crowd = 10 feet

Length of crowd = 1 mile = 5280 feet

Area of crowd = $Length \times Breadth$

                       = $5280 \times 10$  

                       = $52800ft^2$  

1 person occupy space = 2 sq.feet

No. of persons occupy $52800ft^2$  space :

= $\frac{52800}{2}$

= $26400$  

Hence the number of people watching the parade is 26,400

Answer 2

We know that on each side of the street it is 10 feet deep and 1 mile long, which 1 mile = 5280 feet. So, lets get the area first.

First get the area of one side of the street. Note *  means to multiply

10ft * 5280ft = $52800\ ft^2$

We know that one person occupies 2 square feet so

1 person = $2\ ft^2$

We take 52800 and divide it by 2, which 2 represent 1 person

26400 / 2 = 26400

Now we know that one side represent 26400 people. We have two sides so we times this by 2

26400 * 2 = 52800 people

Answer = 52,800
