Find the area of a square with sides of length

1/3
yard.

To find the area of a square with sides of length 1/3 yard, we need to use the formula:

Area = side length x side length

Substituting the given value, we get:

Area = (1/3) yard x (1/3) yard

Area = 1/9 square yard

Therefore, the area of the square is 1/9 square yard.
