To find out the height of the building, we can set up a proportion using the information given.
The proportion can be set up as follows:
Height of the tree / Length of the tree's shadow = Height of the building / Length of the building's shadow
Plugging in the values:
11 feet / 8 feet = Height of the building / 22 feet
Now we can solve for the height of the building by cross-multiplying:
8 * Height of the building = 11 * 22
Height of the building = (11 * 22) / 8
Height of the building = 242 / 8
Height of the building = 30.25 feet
Therefore, the building is approximately 30.25 feet tall.
