I'm no mathematician so what am I doing wrong?
You're absolutely right... I worded my sentences wrongly.

..7,000 acres = 10.9 square miles - not a square 10.9 miles on a side.
47,000 acres = 73.4 square miles - not a square 73.4 miles on a side.

So then, 73.4 square miles would be like a square ~ 8.6 miles on a side.
That's much more reasonable for the spread of a wildfire than what I was thinking.

Thank you for catching my errors
