I found it on website. I don't understand how it is possible, so if somebody is able to explain this to me I will be grateful :)

It is a geometric "optical illusion". It involves some cheating. The rectangle is not actually covered by the 4 pieces. The missing area is covered by the lines, which have finite width.

 

A better explanation can be found here.

Thank You ;)

Somehow I think it's amazing to create an illusion like this one.
