A building casts a shadow 54 feet long at the same time a 6 foot tall man casts a shadow 4 feet long. How tall is the tree?

Huh??

It would help if you proofread your questions before you posted them.

What tree?

If the building:

x/54 = 6/4

Solve for x.

81

To find the height of the tree, we can set up a proportion using the information given.

Let's assume the height of the tree is h feet.

According to the information, the building casts a shadow 54 feet long, while the man casts a shadow 4 feet long. Therefore, we can write the proportion:

(Height of Building) / (Length of Building's Shadow) = (Height of Man) / (Length of Man's Shadow)

This can be written as:

h / 54 = 6 / 4

To solve for h, we can cross multiply:

4h = 6 * 54

Multiply 6 by 54:

4h = 324

Divide both sides by 4:

h = 324 / 4

Simplifying:

h = 81

Therefore, the height of the tree is 81 feet.
