The question must have been made a little clearer. If the correct answer is 100, then they might be asking for the perimeter of the above figure.

The answer won't count the middle line. Because if you see, the middle line is drawn only to show the shape of the triangles and squares. Or else, it really isn't there. So that way 100 is the answer.

But the plastic wire is bent in the middle too, as shown in the figure. But the middle line is not considered? The answer should be 120, not 100. Its coming for me by including the middle line. Please define it clearly. Requested

The length of wire is 20, so the length of each side of each shape is 5. Now, if we count the number of times the piece of wire has come, it's 24 times. So, the answer is 120. But, if we consider the answer without the middle wire, we will remove 20 from it which makes 100 the answer. Although, I think it should technically be 120.
