Walking trails AC and BD represent the diagonals of the parallelogram ABCD. As known the diagonals of the parallelogram bisects each other.

Then

  • DE=BE;
  • AE=CE.

Since DE=BE, then

y+2=3y-4,

2y=6,

y=3.

And BD = y+2+3y-4=3+2+9-4=10 miles.

Since y=3 miles and AE=CE, then

AC=2CE=2(2y-3)=2(6-3)=6 miles.

The  sum of the lengths of the two trails is

AC+Bd=10+6=16 miles.
