Answer: (A)
12+12√(12) .

Explanation:

Perimter is the sum of the all sides of a figure.

As the given design has three exactly same or identical triangles with side-lengths
2√(2)\ in, 2√(2)\ in, 4\ in joined by ending vertices.

Then, the combined operimetr of thge design would be :

3 x (Perimeter of the one triangle)

For this , Perimeter of one triangle =
2√(2)+2√(2)+4\ in =(4√(2)+4) = 4(√(2)+1) \ in

Now , the combined operimetr of thge design would be :


3*4(√(2)+1)=12(√(2)+1)\ in or
12+12√(12)\ in

Hence, the correct option is (A)
12+12√(12) .
