Answer :
We have 1.1 x 10^5 square nautic miles.
1 nautic mile = 1.852 km
[tex]\begin{gathered} 1.1x10^5(Nautic\text{ miles})^2=1.1x10^5\text{ Nautic miles x Nautic miles }= \\ =1.1x10^5Nautic\text{ miles x (}\frac{1.852\operatorname{km}}{1nauticmile})xNautic\text{ miles }x(\frac{1.852\operatorname{km}}{1nauticmile})= \\ =1.1x10^5x1.852kmx1.852km=1.1x10^5x(1.852)^2km^2=3.8x10^5km^2 \\ \end{gathered}[/tex]Answer: 3.8x10^5 km2
