AnnyKZ [126]

Answer:

The land area of Florida is 170,000\ mi^2

Step-by-step explanation:

Let

x -----> the land area of Alaska in square miles

y -----> the land area of Florida in square miles

we know that

The linear equation that represent this problem is equal to

y=\frac{1}{10}x ----> equation A

x=1,700,000 ----> equation B

substitute equation B in equation A and solve for y

y=\frac{1}{10}(1,700,000)=170,000\ mi^2

Remember that

Florida's land area is one-tenth the size of Alaska is the same as to say that Alaska's land area is ten times the size of Florida
