The side b = 136 as I think it’s the two equal sides
If you divide 13.1 by 2.75 you'll get 4 plus a remainder so we know there are 4 stops at 2.75 intervals. 4*2.75=11. Subtract 11 from 13.1 and the last stretch would be 2.1 miles.

I don’t really know about the others sorry!
B I think hopes this helps
