1 yard of fabric has a length of 1 yard but the width of the fabric is not specified and so the question cannot be answered.
You would need one yard. Fabric is cut in one-fourth yard cuts. Three-fourths of a yard would be 27" which is not enough. To get the 30" length, you would need one yard and would have 6" left over in length. Most fabrics are at least 36" wide, so you would have some fabric left over in width also.
It is simply the length of the fabric so 1 [linear] yard.
Fabric is usually either 45" or 54" width (depends on the bolt), and one yard is 36" length. So 0.50 yards of fabric is either: 18" length x 45" wide OR 18" length x 54" wide

one half yard?
One yard of fabric is 36" long, and varies in width. If you have 45" wide fabric, you need 22" of fabric (less than one yard). The fabric store can help you with that.
Assuming each square has a side length of 6 inches, you can cut 16 squares from 1 yard of fabric. This is because 1 yard is equal to 36 inches, and each square requires 6 inches of fabric for one side.
If the table is 36" round, I'm assuming you are talking about diameter. I would simply get the same length as the width of the fabric you want to use. Then the drape will be the same....
In a yard of fabric, there are 3 feet in length and the width can vary but is typically around 36 inches. To calculate the total square footage in a yard of fabric, you multiply the length (3 feet) by the width (36 inches) and convert the result to square feet. This gives you a total of 9 square feet of fabric in a yard.
1 yard = 3 feet. It doesn't matter what it's a foot or yard of (fabric, rope, etc.) because one yard of anything will always be the same as three feet of anything.
Unless I misunderstand the question, it is a yard (36 inches), which has nothing to do with its width. A yard of length is always 36", it has nothing to do with the width which could be from 42" to 60".
