Two vertical (shown in the diagram) are placed 6 ft from the center of the building. How long should they be. Show a diagram in your explanation

Since the two vertical lines are placed 6 ft from the center of the building, and assuming the building has a rectangular shape, we can draw a diagram as follows:

|--- 6 ft ---|
----------------------------
| |
| Building |
| |
----------------------------

Now, let's assume the length of the two vertical lines is x ft. We can then draw another diagram with the vertical lines included:

|--- 6 ft ---|
----------------------------
| | |
| ______ | |
| | | | |
| | x | | |
| | | | |
| |______| | |
| | |
----------------------------

In this diagram, the vertical lines are represented by the two lines with a length of x ft. The building is depicted with rectangular shape.

Since the vertical lines are 6 ft from the center of the building, we can divide the distance from one end of the building to the center into two equal parts, each of which is 6 ft. Thus, each vertical line will be x ft long.

Therefore, each vertical line should be 6 ft long.
