A square yard is a measure of area in 2-dimensional space. A length is a measure in 1-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.
250 square feet = ~27.8 square yards.
You multiply the width by the length to get the area. In this case the answer would be 250 square feet or 27.78 square yards.
Its length is 100 square yards.
The length of the sides of a square if it covers 222 square yards is: 14.9 yards.
Multiply the length of yards by the width of yards. That will give you the square yards.
27.7778 square yards.
You cannot convert square yards to yards. If you have a real quadratic square with an area of 4800 square yards, then you can calculate one side length as the square root of 4800. The square of 4800 sqare yards has a side length of 69.2820323 yards.
A square with a side length of 12 yards has an area of 144 square yards.
A square with a side length of 29 yards has an area of 841 square yards.
354.166... square yards.
2.000 * * * * * 250 inch = 6.944... yards so 250 inch squared = 6.944... yards squared. That is a square with sides of 250 is the same as a square with sides of 6.944... yards. That is NOT the same as 250 sq inches, which is 0.1929 sq yards (approx).
That is impossible. A yard is a measure of length or distance and a square yard belongs to an area. If it means that 75 square yards is the "area of a real square", then the side length of this square is 8.660254038 yards.
