An artist is painting a large mural comprised of different sizes squares. She wants to pain one magenta square that is as large as possible, but she only has one can of magenta paint. If the can of paint can cover 220 square feet, what is the side of the largest square that she can paint if she needs to apply 2 coats of paint?
Round to the nearest whole number.

110 sq ft pre coat, so side=sqrt(110)=10.5 ft
