The low-tech approach: redraw the figure.
We are told there are 6 identical squares, each with side length 1.
One square "sticks out" on each side of the figure.
All side lengths are the same.
One square added to a side of the 4x4 square (of two edge lengths ) adds 3 extra sides of equal length no matter where you put the extra square.
The drawing irritated me.
So I moved the lone squares up to make each one flush with the top.
Then I put dots on the sides that constituted the perimeter, and counted dots.
The outer perimeter equals 12.
Answer B
