Passionate and commanding
Answer: 20
Step-by-step explanation:
You find the mean by adding up all the numbers in a data set, then dividing by the number added.
18 + 15 + 22 + 18 + 25 + 19 + 23 + 20 = 160
We added 8 numbers together, so we divide 160 by 8
160/8 = 20
The sum (for all polygons) of the exterior angles are 360. So, 360/11 is 32.72

Area = Side x Side meaning it's 12 x 13 = 156
Area = 156
