Given that the area of a rectangle is represented as A=l x w, where l =length, and w=width, and that a square is just a rectangle where all the sides are the same, the area of this square would = 2 feet x 2 feet. That yields a prodcut of 4 square feet, which is the area you would need to cover in poured concrete.

how may yards of concrete are needed for a floor 24 x 25 feet?
It is impossible to answer the question as asked because square feet is a measure of area and a "yard of concrete" actually refers to a cubic yard of concrete. However, if we make a couple assumptions we can answer the question I THINK you're asking which is, "How many square feet of concrete does one cubic yard of concrete yield if poured to a typical depth of 4 inches?" The inches of depth can be changed to suit the situation, but in any case giving the poured concrete a depth turns it into a volume which makes it easier to compute the area a cubic yard of concrete will cover. To begin, we need to convertt the square footage of concrete (which is an area) to a volume. Let's use 6 inches for the depth: 12" x 12" x 6" = 864in^3 or 864 cubic inches This is the number of cubic inches of concrete in one square foot of concrete poured to a depth of 6 inches. Now we put a cubic yard into the same terms, cubic inches: 36" x 36" x 36" = 46,656 in^3 or 46,656 cubic inches of concrete. Now we simply divide number of cubic inches of concrete in a yard of concrete by the number of cubic inches in a square foot of concrete poured to a depth of 6 inches: 46656 / 864 = 54 square feet. By the way, there are 27 cubic feet in a cubic yard and you may notice that 27 x 2 = 54. That's a result of the depth I chose for the poured concrete--6 inches. A square foot of concrete poured to a depth of 6 inches is equal to one half cubic foot of concrete. 27 / .5 = 54 If you want to figure square foot yield per yard when you pour the slab at 4 inches instead of 6 inches, then simply substitute 4" in the equations for 6". (36" x 36" x 36") / (12" x 12" x 4") = 81 square feet.
A yard of Concrete is 3ft x 3ft x 3ft volume. It is usually poured over a 2" gravel sand mix for an additional four inches. So it should cover 36 "/4" = 9 (x 3ft x 3ft), or 81sq ft.The 'square feet' of area that it covers is 324/(depth of the concrete, in inches)
One square yard is nine square feet, so 27 square feet is equivalent to 3 square yards. So 3 yards of concrete will cover 27 square feet.
1 cubic yard of concrete fills 27/depth in feet square feet.
To calculate the amount of concrete needed to cover a driveway that is 9 feet wide and 150 feet long, you first find the area by multiplying the width by the length: 9 feet × 150 feet = 1,350 square feet. The depth of the concrete layer is also needed to determine the volume. For example, if you want a thickness of 4 inches (0.33 feet), the volume would be 1,350 square feet × 0.33 feet = 445.5 cubic feet.

If it is the same as concrete it will cover 162 square feet. concrete covers 81 square feet by 4" deep
9 square feet.
A cubic yard of concrete covers an area of 81 square feet when poured at a thickness of 4 inches. This is calculated by dividing the total volume of the cubic yard (27 cubic feet) by the thickness in feet (1/3 foot for 4 inches), resulting in 27 ÷ (1/3) = 81 square feet.
