Answer 1

Humans measure long stretches of time in units such as years, decades and centuries. A decade is ten years, and a century consists of one-hundred years.

Answer 2

Explanation:

decade is a period of 10 years. The word is derived (via French and Latin) from the Ancient Greek: δεκάς, romanized: dekas, which means a group of ten. Decades may describe any ten-year period, such as those of a person's life, or refer to specific groupings of calendar years.
