Explanation:

Here is the complete question

A tree is standing behind a building. 2/5th of the height of the tree can be seen and the rest is hidden by the building. The building is 12 metres high. What is the height of the tree?

If 2/5 of the tree can be seen the tree covers ( 1 - 2/5) 3/5 of the tree. If the building is 12 metres high, it means that 2/5 of the building is 12m high

the height of the tree = 12 x (5/2) = 30m
