Question

12 people fit comfortably in a 5 x 5 foot square.use this value to estimate of a crowd that is 10 feet deep on both sides of the street along a 1 mil section of a parade route

Answer 1

48 people

Explanation:

It states that 12 people fit into a 5 x 5 ft² area.

Here, we are given the length and breath of the side, both 5 ft. And from that, we can estimate the area of the place.

Area of a square is gotten by multiplying both sides together, and thus

5 * 5 = 25 ft²

We are told 12 people fit into 25 ft². In order to get the number of people that fit a 10 x 10, we first need to calculate the area.

We already have the length and breadth to be 10 ft each, so

Area = 10 * 10 = 100 ft²

Now, we calculate.

If

12 people fit into 25 ft²

x people will fit into 100 ft²

If we cross multiply, we have

1200 = 25x

We then divide both sides by 25

x = 1200 / 25

x = 48

Therefore, 48 people will fit into a 10 x 10 ft area
