Each field has different dimensions, therefore different distances to the fences.
The dimensions are 7 by 12 meters Check: perimeter = 2*(7+12) = 38 meters and area = 7*12 = 84 square meters
It is not possible to answer this question without knowing the shape of the field - circular, triangular, rectangular, etc.
Since the dimensions of a standard football field are 105 x 68m, and a football field is a rectangle, then 105 + 68 + 105 + 68 = 346, so the perimeter is 346m.
The length is 10 meters and the width is 5 meters
