What is the explanation to this question? is the "figure" the whole shaded region or the triangle created with AB as hypothenuse?

This becomes a triangle which has the angles in the ratio of \(45:45:90\) or \(x:x:x\sqrt{2}\)
We do know this because the segment AB is \(8\sqrt{2}\)
which means that the other sides are 8
One side of a square is 4.
We want to know the perimeter of the shaded region which has 10 sides
\(4 \times 10 = 40\)
C is the answer
