The square of rectangles

The square of rectangles

We have five rectangles whose sides have the following lengths: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 although not necessarily in this order. With these five rectangles, we can form a larger square.

What is the length of said square?


The image shows the square formed by the different rectangles. The length of the resulting square is therefore 11.
