Answer: lenght = 13.86 units
Centroid = (4.3,7.3)
Step-by-step explanation:
Median through A bidects the opp. side BC
Mid. Point of BC(M) = {(-9+18)/2,(13+7)/2}
= (4.5,10)
Length of median = lenght of AM
= √(y2-y1)^2+(x2-x1)^2
= √(10-4)^2+(4.5+8)^2
= √36+156.25
= 13.86 units
Centroid = {(4-9+18)/3,(-8+7+13)/3}
= (13/3,22/3)
= (4.3,7.3)
Centroid = (4.3,7.3)
