The length would be 18 inches and the width would be 9 inches since the length is twice its width and to find perimeter you do length x 2 and width x 2 and add it together so 18x2 = 36 and 9x2 = 18. 36 + 18 = 54

A football field is 120 yards long (100 yards playing field plus 2 end zones 10 yards each) by 53 1/3 yards wide.

1 yard = 3 feet.

120 yards x 3 feet per yard = 360 feet

53 1/3 yards x 3 = 160 feet.

The area of the football fields is 360 x 160 = 57,600 square feet.

1 bag covers 2000 square feet:

57,600 / 2,000 = 28.8 bags, round up to 29 bags are needed.

1 bag cost $27.79.

29 bags x $27.79 = $805.91 total cost.
