Question

By using shadows, Tatiana wants to find the height of a building. At a certain time of day, her shadow is 2.4 feet long and the building’s shadow is 16 feet long. Her height is 5.8 feet. How tall is the building?

Answer 1

9514 1404 393

Answer:

38 2/3 feet

Explanation:

In shadow problems, the usual assumption is that object height and shadow length are proportional.

height/length = b/16 = 5.8/2.4 . . . . . for building height b

b = 16(5.8/2.4) = 38 2/3

The building is 38 2/3 feet tall.
