Don't laugh at me lol...it says Jamal is 5 feet tall. One sunny morning he notices that he casts a shadow that is 2 feet long. If the school building casts a shadow that is 7 feet long at the same time, what is the height of the building?

Answer 1

Why would we laugh?

Use a proportion.

5/2 = x/7

Cross multiply and solve for x.
