Answer:
40
Step-by-step explanation:
If points A, B, C are midpoints of sides XY, YZ, ZX respectively. Then by midpoint theorem.

XY = 2*20
XY = 40
The median is 90.125 because since there is no middle because it’s an even number you add the middle 2 numbers and then divide that by 2

which means the sum of the 100 numbers must be
