Look at the figure ...
Don't get confused with the start points of the corner squares..

How many lines moving left to right - 4
How many moving down to up - 2
So perimeter = 2(4+2)=2*6=12

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

The small square on the left has an outer perimeter of 4 - 1 = 3. The larger square (which is composed 4 smaller squares) in the middle has an outer perimeter of 8 - 2 = 6. The small square on the right has an outer perimeter of 4 - 1 = 3. Thus, the outer perimeter of the entire figure is 3 + 6 + 3 = 12.

Answer: B

Perimeter = (1+1) x 4 + 1 x 4 = 12

We know that all squares have a length of 1 and computing the outer perimeter goes like this :

A. Top and Bottom of the four adjacent squares = 2 + 2 = 4
B. Side square = 2 (four adjacent square side length) - 1 (side square bottom) + 1 + 1 + 1 (side square top left right) = 4
C. We have 2 side squares which therefore 2 * 4 = 8

Add up A + C = 4 + 8 = 12

Therefore B is the answer
