Reyna's house is 12 blocks due west of the school. Shaquille's house is 5 blocks due north of the school. Shaquille walks to Reyna's house every morning and then they walk to school together. What is the shortest distance Shaquille could walk on his way to school when he walks with Reyna?

Looks like 5+12+12
assuming they keep to the rectangular grid of streets.

If he can walk cross-country, then consider the hypotenuse of a 5-12-13 triangle.
