The question as stated makes no sense, as square feet is a measure of area and "yard", is a measurement of volume. Normally, "yard" is a measurement of length. However, concrete, soil, gravel, sand, etc., are normally sold (in the U.S.) by the "yard" which is simply short for "cubic yard."
However, you may easily calculate the area that a yard of crushed rock will cover, depending on the desired depth of crushed rock. As a cubic yard is 3 feet by 3 feet by 3 feet, which is equivalent to 9 square feet by 36 inches, simply divide 36 inches by the desired depth in inches, and multiply it by 9 square feet.
Thus, if you wanted a depth of 8 inches, 36 divided by 8 is 4.5. So, you can cover 4.5 square yards, or 4.5 times 9 square feet = 40.5 square feet, which would be a square area approximately 6 feet 4 inches by 6 feet 4 inches.
1 cubic yard of crushed rock fills 3/depth in feet square yards.

There are about .836 square meters in a square yard.
There are no square feet in a yard (yard is one-dimensional, square foot is two-dimensional). However, there are 9 square feet in a square yard.
1 cubic yard of crushed rock fills 3/depth in feet square yards.
how many tons of rock are in a yard?
Volume = (84) x (1/6) = 14 cubic feet = 0.52 cubic yard
how many tons of rock are in a yard?
This depends on how much rock you will use per square yard. Suppose you intend to use 1/100 tons (=20 lb) per square yard. Then if you have one ton of rock, it will cover 100 square yards. Similarly, if you intended to use 1/50 tons per square yard, 1 ton will cover 50 square yards. In general you want to use factor labeling: If you are using x tons per square yard, then write this as (1 square yard) / (x tons of rock) = (1/x)*(square yards/tons of rock) This is called a conversion factor. Now, if you have some quantity of rock, say y tons of rock, and you want to see how many square yards it would cover you just multiply (y tons of rock)*(1/x)*(square yards/tons of rock) = y/x (square yards*tons of rock/tons of rock) = y/x square yards since the labels just divide out.

One square yard is just that. One yard wide by one yard long. It is one square yard.
1 square yard = 8,361.27 square centimeters.
One square yard is 0.000000836127392 square km.
There are about .836 square meters in a square yard.

Cubic means a three-dimensional volume. Square means a two-dimensional flat area. The area that can be covered by a cubic yard of rock will depend on how deep the rock bed will be.
