Item description
The problem is to arrange some pieces to make a rectangle with no hole inside.
The five pieces without the square will form a rectangle, and also all the pieces will another one.
In general, the size of a goal is a key to solve for square-making problems.
But, it is not so useful for rectangle-making.
If you solve, please consider a relationship between two rectangles.
You will find an easy way of transforming one to the other.
