b = "7 miles", l = "14miles"

Explanation:

Let the length be l and the breadth be b. Thus, according to question,

lxx b = 98

l(l-7)=98

So

l^2-7l=98

l^2-7l-98=0

l^2-14+7l-98=0

l(l-14)+7(l-14)=0

l+7(l-14)=0

l=-7, l=14

Since length cannot be negative, the length of the field is 14 miles and the breadth is 7 miles.
