Yes, the correct answer is 24 cm2.
If the dimensions of triangle B are three times the dimensions of triangle A, then the ratio of their areas will be 1:9 (since area is proportional to the square of the dimensions).
So, if the area of triangle B is 72 cm2, then the area of triangle A would be 1/9 of that, which is:
72/9 = 8
Therefore, the area of triangle A is 8 cm2.
