The he dimensions of square A are three times the dimensions of square B. The area of square B is 324 cm. What is the area of square A .

3,078 cm
972cm
2,916cm
81 cm

972 cm

Let the length of the sides of square B be x. Therefore, the area of square B = x^2 = 324 cm^2.
Solving for x, we get x = 18 cm.

Since the dimensions of square A are three times the dimensions of square B, the length of the sides of square A = 3x = 3(18) = 54 cm.

Therefore, the area of square A = (54)^2 = 2,916 cm^2.

The correct answer is 2,916 cm.
