Hello! To solve this question, we can write and solve a proportion. Set it up like this: 5,880/x = 42/100. You do this, because you’re looking for the total amount of area there is. Cross multiply the values and you get 588,000 = 42x. Now, divide each side by 42 to isolate the “x”. 588,000/42 is 14,000. x = 14,000. Arizona’s total area is 14,000 square miles.
