C. 32 cm2
Since the dimensions of rectangle B are twice the dimensions of rectangle A, we can say that if the dimensions of rectangle A are x by y, then the dimensions of rectangle B are 2x by 2y.
The area of rectangle B is 128 cm2, so we have:
2x * 2y = 128
4xy = 128
xy = 32
Therefore, the area of rectangle A is 32 cm2.
