No the bible does not give the correct age of Boaz.
No, in the book of Ruth, Boaz is not specifically mentioned as being 80 years old and Ruth as 40 years old. The age of the characters is not specified in the book.
The Bible does not say, but because this marriage of Ruth and Boaz was blessed by God and their grandson David was a man after God's own heart, I think it can be safely assumed that Boaz died at a ripe old age.
