The total area is about $66,000\ mi^2$.

Work Step by Step

Plug the values into this equation, where b is one value, p is the percent, expressed as a decimal, and a is p percent of b. $a=p\%\times b$ substitute $11,800=0.18\times b$ divide both sides by 0.18 $11,800\div0.18=0.18b\div0.18$ simplify $65,555.\overline5=b$
