Final answer:
To find the height of the tree, a proportion is set up using the given information. The height of the tree is calculated to be 36 meters.
Step-by-step explanation:
To find the height of the tree, we can set up a proportion using the given information. Let's say the height of the tree is represented by x. According to the problem, 1/3 of x is above the height of the building. Since the height of the building is 12m, we can write the proportion as: (1/3)x = 12.
To solve for x, we can multiply both sides of the equation by 3: x = 12 x 3. This gives us x = 36 meters as the height of the tree.
Therefore, the height of the tree is 36 meters.
