Impossible Puzzle – Can You Solve It?

The Puzzle fits perfectly before the re-arrangement.

But when the pieces are re-arranged, the Empty area Magically appears.

Can you explain How??

My conclusion in my last comment is not clear.

Width of Left side piece is higher than widthof Right side piece, hence a small gap is appearing.

let us mark the top triangle piece as no. 1
Left side piece as no. 2
the Two small “L” shapes pieces as 3 and 4
Right side piece as no. 5

From shape, we understand that area covered by piece no. 2 is < area covered by pieces 3+4+5.

Conclusion: Area covered by piece no. 2 is width of piece no. 5

Hope, it is clear now

The puzzle fits “perfectly” in the “no-gap” configuration. In the second configuration, with a “gap,” it no longer fits “perfectly.” The bottom right hand edge of the lower “L” piece sticks out a bit. The “border” of the puzzle helps to “hide” the overhang!

It is obvious!!
See the difference between the first arrangement and the second arrangement at the top corner before he puts them back,

The upper triangular piece place it to down and other 4 shapes place it to upper side as it fixes. hope solves.

The position of the 2 small pieces and their relation to each other has been altered, this is due to the piece on the right hand side is wider than the other. The empty space presents the difference in the areas of the other two pieces.

None of the answers are convincing.
Although, I don’t have an answer, I did not find any of the explanations convincing.
Technically, the area is same as before, so where does the new space come from ?

In the first arrangement, the pieces were not fixed that tight. There was invisible gap between them. Next arrangement they were fixed really tight with a visible gap.

This small gap resulted from the compression of pieces of puzzle after they are rearranged whereas they have been relaxed before the rearrangement.

width and height of 2 pieces that have been replaced with each other varies resulting in the visible gap because two L shape pieces sit on each other instead of fitting into each other because of the width variation.

some of the parts appear to be bent and not perfect straight line

This small square gap results from the excess area of the very thin rectangle in the lower bottom of the bigger piece.
