Answer :
Final answer:
The width of the rectangular athletic field is 20 yards and the length is 40 yards, based on the provided conditions and the formula for the perimeter of a rectangle.
Explanation:
This is a problem of geometry and algebra. The question states that a rectangular athletic field is twice as long as it is wide. If we label the width as x, then the length would be 2x. The formula for the perimeter of a rectangle is 2(length+width), so substituting the given values, we get 2(2x + x) = 120 yards. By simplifying this equation, we get x = 20 yards. Therefore, the width of the field is 20 yards and the length of the field is 40 yards.
