Problema Solution
In a loose crowd, each person takes up about 10 square feet. What is the best estimate of how many people gathered for a protest demonstration that loosely filled a plaza that measures 100 yards by 40 yards?
Answer provided by our tutors
Let 'x' represent the number of people that filled the plaza.
The area of the plaza is:
A = 100*3*40*3 ft^2 (since 1 yd = 3 ft)
A = 36,000 ft^2
10x <= A
10x <= 36,000

x <= 3,600
There were not more than 3,600 people at the protest.
