The limiting floor ratio is 0.45 to 1, this means that we have the ratio 0.45:1.
Let x be the new remodel sizem since at first we had 11800 squared ft now we have a ratio x:11800.
Equating the ratios we have the proportion:
[tex]\frac{x}{11800}=\frac{0.45}{1}[/tex]Solving for x we have:
[tex]\begin{gathered} \frac{x}{11800}=\frac{0.45}{1} \\ x=0.45(11800) \\ x=5310 \end{gathered}[/tex]Therefore the maximum size is 5310 squared ft.
