How Long Is The Length?

I have designed a simple math quiz that I would like anyone who is interested to try.

The catch is :

- No manual counting of the units.

- To be done within 10 sec.

This is a rectangular maze made up of 12 units by 13 units.

The width of the path within the maze is 1 unit.

Question: How long is the length from cell "S" to cell "E"?
