109.72800 metres is how long the football field is.
In general we know 
1 meter = 1.09361 yard.
So we can say 
 
1 yard = [tex] \frac{1}{1.09361} [/tex] meter
           = 0.9144 meter.

So 120 yards = [tex]120 * 0.9144[/tex] meter
                      = 109.728 meter.

So length of football field is 109.728 meter.
