Answer:
25 feet
Step-by-step explanation:
This is a ratio question.
Say the ratio is object : shadow. Then, the person and their shadow is
5 : 4
If the shadow is 20, then the ratio is
flagpole : 20
How do you go from 4 to 20? You multiply by 5. So, if we multiply the person's height by 5, we'll get the height of the flagpole.
5 * 5 = 25 feet
