Yes that is correct.
100x365.25=36,525 days "100 years = 36,525 days because of the leap years." This is close, but not correct. Leap years do NOT occur on centennials (for example, 2000) except I think every fourth one. The absolutely correct answer to this question is 36,524.22, but for simplicity's sake you could say 36,524.

The correct spelling is triennium (a period of three years).
'Since the last ten years...' is correct, but is only part of a sentence.
32 Years, If My Math Is Correct.

about 10 years if my calculations are correct then it is approximately 114,079,552 years.
Both are adequate
