Length 11 miles and width 6 miles
Explanation:
If the width is taken to be x miles, its length would be x+6 and area would be x(x+6). Thus,
x(x+6)=55.
This can be solved for x by factorising the quadratic expression
(x+11)(x-5)=0. this gives x=5 or -11. Since x cannot have a negative value, it would be x=5
Width is 5 miles hence length would be 6more that is 11 miles.
