Keeper 1: Estimating Crowds SAS 1 #1 & 2

WARM UP What is the largest gathering of people you have ever been involved in? How many people were involved? How do you think the event counted the people?

Area Common shapes and their formulas: Definition: The extent of a two-dimensional surface enclosed within a specified boundary or geometric figure. Common shapes and their formulas:

Estimating Crowds Assumption???

Width: 10 Feet wide Length: 1 Mile long How many feet in a mile? 5,280 feet in a mile What is the area of the crowd? 52,800 square feet

Multiply the ratio by the area ________ x ________ So our ratio is _____? Our Area is _______? Multiply the ratio by the area ________ x ________ Don’t forget both sides of the street! Both sides of the street = x2!!!! Final Answer: ______________

Multiply the ratio by the area ________ x ________ 3. One rule of thumb for estimating crowds is that each person occupies 2.5 square ft. Use this rule to estimate the size of the crowd from question 2. So our ratio is _____? Our Area is _______? Multiply the ratio by the area ________ x ________ Don’t forget both sides of the street! Both sides of the street = x2!!!! Final Answer: ______________

Practice Problem A basketball court is 94 feet by 50 feet. 8 kids can fit next to each other in a 3 ft. by 3 ft. How many kids would you estimate can fit side by side over the entire floor?
