^is that all to the question? Because, in that case it's just the area, multiplied by 2.

However, I believe there ought to be more to it.

Answer 3

No. What Zach wants is the area doubled. So the current area is 27 sq ft.
Doubed that is 54 sq ft. He can increase the length and breadth by a multiple of sqrt2.
