A building is 20 feet tall and a cast a 12-foot Shadow and a person who is standing right next to the building cast a 3-foot shadow how tall would the person be

Answer 1

This is a proportion problem.

20/12 = x/3 => x=5 where x is the height of the person.

BTW: your English needs attention too! The verb "to cast" in the 3rd person singular is "casts".

A complete sentence ends with a period. A question begins with a capital letter and ends with a question mark. The English language is a wonderful precision too; you should learn to use it correctly!
