For Geeks & Brainiacs #04- Twelve Matches -

In the illustration below, twelve matches are arranged in the shape of a square with an enclosed area of NINE square units. Can you rearrange the matches to form a single shape using all twelve matches with an enclosed area of FOUR square units? The matches may not be placed on top of one another (each match must contribute towards the perimeter of the shape).

Note: You can rearrange the matchsticks by dragging them around. You can also rotate a match by clicking on it.
