I will assume that "in the region " means in the rectangular field.
Let's get the area of the field
300*500=150000
so the roadway shouldn't be more than 50000 ft^2
We aren't told the length nor whether the roadway goes around the perimeter or just across the field we don't know the length
Assuming the it is 300+500+500+300 long=1600 ft long
50000/1600= 31.25 ft wide
