A park has a walking track in the shape of an irregular quadrilateral. The four side lengths of the track are $8a$8a m, $6b$6b m, $2a$2a m, and $3b$3b m.
Write an expression for the length of one complete lap around the track.
What is the length of one lap around the track if $a=15$a=15 and $b=5$b=5?
