We can set up a proportion to solve for the height of the tree:
36 inches / 21 inches = x inches / 168 inches
Cross-multiplying, we get:
36 inches * 168 inches = 21 inches * x inches
Simplifying, we get:
x = (36 inches * 168 inches) / 21 inches
x = 288 inches
Therefore, the height of the tree is 288 inches, which is equivalent to 24 feet. The answer is option (C), 288 inches.
