The area of a square garden is 1/36 mi^2. How long is each side?

To find the length of each side of the square garden, we can take the square root of the area.

Given that the area is 1/36 mi^2, the length of each side is √(1/36) = √(1)/√(36) = 1/6.

Therefore, each side of the square garden is 1/6 mile long.
