Question

A building casts a shadow that is 72 feet long. A garage next to the building is 27 feet high and casts a shadow that is 4.5 feet long. What is the height of the building?

Answer 1

The 27 foot tall garage makes a 4.5 foot shadow.

The shadow is (4.5/27) = one sixth the garage height

So the building's shadow should be one sixth times 72 feet or

72 * (1/6) or 12 feet
