Here, land area of two places is compared. Florida's land area is
expressed as a fraction of the other place's land area. A proper
fraction always refers to less than one. If Alaska's land area is
considered as one. Florida's land area is less than that of Alaska. The
statement also tells that Florida is only a tenth of Alaska's size. To
find the fractional value of a number, multiply the number by the given
fraction. Thus 1/10 of 1700000 = 170000
So the approximate land area of Florida is 170000 square kilometers.
