3 mile section that is 9 feet deep on BOTH sides of the street.

6. A city has a population of 15,435. Can the entire population fit onto the football field if
the field is 120 yards long and 75 yards wide? Each person occupies 2.5 square feet of
space.

(Urgent!!! Somebody pls answer both questions) *show work*

Answer 1

5. 38,000 people

6. The entire population fits in the field.

Explanation:

5.

1 mile = 5280 ft

3 miles = 3 × 5280 ft = 15,840 ft

A rectangle 3 miles long and 9 ft wide has the area:

area = 15,840 ft × 3 ft = 47,520 ft²

Since both sides of the street have the rectangle 3 miles by 3 ft, we double the area:

47,520 ft² × 2 = 95,040 ft²

A person occupies 2.5 ft².

95,040 ft² / 2.5 people/ft² = 38,016 people

6.

Length of field: 120 yd

Width of field: 75 yd

Conversion: 1 yd = 3 ft

area of field in ft² = 120 yd × 3 ft/yd × 75 yd × 3 ft/yd

area of field = 81,000 ft²

area occupied by 1 person: 2.5 ft²

number of people = 81,000 ft² / 2.5 ft²/person

number of people = 32,400 people

The field has room for 32,400 people.

There are 15,435 people in the city.

The entire population fits in the field.
