The size of Texas is approximately 270000 square miles this ever represented approximately 41% of the size of Alaska approximate

Tanzania [10]

Let's set up the problem. First, we know Texas is 270,000 square miles, and this is 41% the size of Alaska.
So 270,000=41%(size of Alaska), or 270,000=.41(x). Now solve for x to find the size of Alaska.
