A parade route is 1 mile long. People have lined up 5 feet deep on BOTH sides of the street. Using the ratio of 2.5 square feet per person, estimate the number of people in the crowd.A. 26 peopleB. 132,000 peopleC. 10,560 peopleD. 21,160 people

Answer:D 21,160 peopleStep-by-step explanation:Let's think of the route as a straight line 1 mile long. The area occupied by people is a rectangle on each side of the mile-long route. Each rectangle is 5 ft wide and 1 mile long. When you put both rectangles together, you have one rectangle that is 1 mile long and 10 feet wide. We find the area of the rectangle in square feet and divide by 2.5 square feet to find the number of people.area of rectangle = length * widthA = 1 mile * 10 ftWe need to convert 1 mile into feet.1 mile = 5280 feetA = 5280 ft * 10 ftA = 52,800 ft^2The area of the rectangle is 52,800 ft^2. Since we are using a ratio of 2.5 square feet per person, we divide the area in square feet by 2.5 to find the number of people. number of people = 52,800/2.5 = 21,120 peopleThe closest answer is D 21,160 people
