How do you determine square yards from linear feet?

To determine square yards from linear feet, the correct method involves using both the length and the width of the area being measured. Since a square yard is a unit of area that is equivalent to 9 square feet, the calculation must convert the linear measurement of feet into a more manageable unit by utilizing the dimensions of the surface area.

When you multiply the linear feet by the width and then divide by 9, you are effectively calculating the total area in square feet first, and then converting that area into square yards. This adjustment accounts for the fact that there are 9 square feet in one square yard, which is the foundational step for the conversion.

In other choices, simply multiplying linear feet by length without considering width, dividing linear feet by 9 alone without the area calculation, or adding linear feet and width do not yield a correct determination of square yards since these methods do not follow the area formula or consider both dimensions appropriately. The process requires combining the linear measurement with its corresponding width to ensure an accurate area calculation in square yards.
