Lele I want to bought a sandbox in her backyard the sandbox she build has an area of one do you want to square feet yard drive the sandbox to blow and label the side to show all the possible of21 and widths

Since English doesn't appear to be your native language, I suggest you ask a native-English speaker to help you write your question so that others can understand it.

To determine the sides of the sandbox, we need to find all possible pairs of length and width that have an area of 1 square yard. Here's how you can do it:

1. Understand the conversion: Since we're given the area in square feet, we need to convert it to square yards. There are 9 square feet in a square yard, so the given area of 1 square foot is equivalent to 1/9 square yards.

2. Find the possible dimensions: To find all possible combinations, we can start by finding factors of 1/9 square yards. In this case, the only factor of 1/9 is 1/9 itself. Therefore, the possible dimensions are a length of 1/9 yard and a width of 1/9 yard.

3. Calculate the sides: Now, we need to express the dimensions as whole numbers for ease of visualization. Since both the length and width are already in fractions of a yard, we can simply multiply them by 9 to get whole numbers.

The sides of the sandbox, in yards, would be:
- Length: 1/9 yard * 9 = 1 yard
- Width: 1/9 yard * 9 = 1 yard

Therefore, the sandbox would have sides labeled as 1 yard by 1 yard to represent all possible dimensions resulting in an area of 1 square yard.
