39 miles ------------------------------------------------
Answer:
Step-by-step explanation:
Let the total area be x.
<u>Farm exhibits are in 1/10 of the fairground:</u>
<u>Part of the fairground with rides:</u>
- r = x - f = x - 1/10x = 9/10x
<u>How much greater is the part of the fairground with rides than farm exhibits?</u>
- r/f = 9/10x : 1/10x = 9 times
Assuming that the actual question reads lines b and c are perpendicular to line d
we are given that c is perpendicular to line d and parallel to line a. Since b is also perpendicular to line d, a b and c must all be parallel (draw it out will make a lot more sense)
So b is also parallel to line a
