Question

a skyscraper which has a base that reaches 234 below ground rises 1574 feet. What is the building's elevation?

Answer 1

I think this question is saying that the total length of the skyscraper is 1574 feet, of which 234 feet are below ground.  So they want you to find the length of the skyscraper that is above ground, which is 1574 - 234 = 1340 feet.
