The inequality which best describe the third side of the triangle which has two sides of unit 20 and 31 is 20>b>31.
<h3>What is triangle inequality theorem?</h3>
Triangle inequality theorem of a triangle says that the sum of the two sides of a triangle is always greater than the third side.
Suppose a, b and c are the three sides of a triangle. Thus, according to this theorem,
(a+b)>c
(b+c)>a
(c+a)>b
The two sides of the triangle are 20 and 31. From the inequality theorem, the another side b can be represented as,
(20+31)>b
Thus, the length of b can be between 20 and 31.
20>b>31
Hence, the inequality which best describe the third side of the triangle which has two sides of unit 20 and 31 is 20>b>31 .

Answer:
Paleolithic or Old Stone Age took place between 3.3 million years ago to 11,650 years ago.
It comprises most of the hominins presence on the planet! It is divided into three sub-periods based on the technology and artifacts humans used.
During the Lower Paleolithic hominins lived as hunter-gatherers and used rudimentary stone tools.
Some 50,000 years ago, humans developed more complex artifacts and tools. We can find evidence of fishing and elaborated weapons. There's also evidence of the first forms of religious ceremonies and art.
The Paleolithic ends with the extensive use of Agriculture.
