12cm to 36cm is mulitiply by 3, so that means that you mutiply each of the other sides by 3 to get your answer

Answer 2

A=30cm, B=39cm

Explanation:

They are an enlargement. Therefore, the sides are larger by the same proportion, otherwise, it wouldn't be an enlargement. Therefore, the bottom side of the big one is 3 times that of the small one. Therefore, the other sides are also 3 times, making A = 30cm and B = 39cm.
