Question

If a 18ft tall free casts a 15ft long shadow then how tall is a lawn ornament that casts a 5ft shadow?

Answer 1

6 ft

Explanation:

First, find the ratio of the tree and its shadow.

18:15

Simply it:

6:5

Therefore, for every six feet an object is, 5 feet its shadow is.

So since the ornament has a 5ft shadow, the lawn ornament must be six feet tall.

Answer 2

6 ft

Explanation:

18 * 5 = 90

90 / 15 = 6
