Answer:
One way to find the area of a square with a side length of 12 yards is to use the formula A = s^2, where A is the area and s is the side length. Since 1 yard equals 3 feet, we can convert the side length to feet and then square it to get:
12 yards = 12 x 3 = 36 feet
A = 36^2 = 1296 square feet
Another way to find the area is to use the fact that the area of a square is equal to the length of one side squared, and the length of one side is equal to the square root of the area. So we can find the area of the square in square yards first, and then convert it to square feet:
Area in square yards = side length in yards squared
= 12 yards x 12 yards
= 144 square yards
Since 1 yard equals 3 feet, we can convert square yards to square feet by multiplying by 9:
Area in square feet = 144 square yards x 9
= 1296 square feet
