Question

In Ms. Ford's classroom 13 students are able to fit comfortably into a 5 by 5 square.

Use this value to estimate the size of a crowd that is 10 feet deep on both sides of the street standing
along a 1-mile section of a parade route.

Answer 1

Estimate of crowd is 27456.

Explanation:

Given that a square of 5 by 5 can have 13 students.

Area of a square =
`side^2` = 25

Area of 25 can have 13 students.

Now, it is given that 10 feet square are used for crowd.

Area of square of side 10 feet = 100

So, area of 100 can have 13
`*` 4 = 52 people from crowd

Now, it is given that the parade route is 1 mile long.

1 mile = 5280 feet

1 mile = 528
`*` 10 feet

It means that there are 528 number of such squares on the 1 mile section of the parade route.

Kindly refer to the attached image as well.

So, number of people or the estimate of the size of crowd is:

528
`*` 52 = 27456
