Rajat drove for 4 km from point A, towards the west. He took a left turn and drove for 4

km. He took a left turn again and drove for 8 km and then he took a right turn and

drove for 3 km. Again, he took a right turn and drove for 4 km. At last, he took a right

turn and drove for 6 km and stopped at point B.

How far (shortest distance) and towards which direction should he drive in order to

reach point A again?

(All turns are 90° turns only, unless specified.)
