5/18 square miles
To find area, multiply the length (5/6) by the width (1/3). To multiply fractions, you multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator.
Start by multiplying the numerators.
5 * 1 = 5
Now multiply the denominators.
6 * 3 = 18
Now, just put them together to get 5/18 square miles.
