1 yard = 3 feet
P = 2L + 2W
1 mile = 5,280 feet
P = 2L + 2W
1 mile = 5,280 feet
There are 3 feet in a yard, so to find the length in feet, we multiply the given length of 53 1/3 yards by 3:
53 1/3 yards * 3 feet/yard = (160/3) feet = 53 1/3 * 3 = 160 feet
Similarly, for the width, we multiply the given measurement of 120 yards by 3:
120 yards * 3 feet/yard = 360 feet
Therefore, the dimensions of the football field in feet are 160 feet by 360 feet.
To calculate the length of the chalk line placed around the perimeter of the football field, we need to find the perimeter of the field. The perimeter is the sum of all sides of the rectangle.
Perimeter = 2 * (length + width)
Perimeter = 2 * (160 feet + 360 feet)
Perimeter = 2 * 520 feet
Perimeter = 1040 feet.
So, the length of the chalk line placed around the perimeter of the football field is 1040 feet.
For part C, to determine how many laps around the perimeter of the field would equal 1 mile, we need to convert miles to feet.
There are 5280 feet in a mile. So, to find the number of laps, we divide the total length of 1 mile by the perimeter of the field.
Number of laps = 5280 feet / 1040 feet
Number of laps = 5.08 laps (rounded to two decimal places)
Therefore, approximately 5 laps around the perimeter of the football field would be equal to 1 mile.
