Answer:
hey! been a while since I've answered questions haha
typically I would put an explanation for my answers but this one's pretty straightforward so ¯\_(ツ)_/¯
a) mode is the number that occurs most often in a data set.
b) mean is the average or expected value in the data set
c) median is the value that lies in the midpoint in the data set.
35
since m and n are the midpoints of ab and ac resistively
then ,bc=2mn=16
since m and l are the midpoints of ba and bc respectively
then, ac =2mn =10
then,nc =1/2 × 10 =5
similary, mb=6
then ,perimeter=nc+mb+mn+bc=5+6+8+16=35
