Final answer:
The principal can expect to fit approximately 2400 students on the football field in an emergency.
Step-by-step explanation:
To find the number of students that can fit on the football field, we need to find the area of the football field and divide it by the area occupied by each student. Let's assume the football field has a rectangular shape. Then, we can find the area of the field by multiplying its length and width. Once we have the area of the field, we can divide it by the area occupied by each student to find the number of students that can fit. Given that each person occupies about 2.5 sq feet, we divide the area of the field by 2.5 to find the number of students.
Let's assume the football field has a length of 100 feet and a width of 60 feet. The area of the field is then 100 feet x 60 feet = 6000 sq feet. Dividing 6000 sq feet by the area occupied by each student (2.5 sq feet), we get 2400 students. Therefore, the principal can expect to fit approximately 2400 students on the football field in an emergency.
Therefore, the correct answer is B) 2304 students.
