A.Jarak eucledian
Rumus ---> De(p,q,r,s) = [(x-s)2+(y-t)2+(z-u)2+
(w-v)2]1/2
A,B = [(1000-870)2 + (20-7)2
+ (10-29)2 + (200-148)2]1/2 = √20134
A,C = [(1000-1100)2 + (20-0)2
+ (10-250)2 + (200-10)2]1/2 = √104100
A,D = [(1000-900)2 + (20-20)2
+ (10-10)2 + (200-170)2]1/2 = √10900

B. Jarak D4 (jarak city-block)
-----> Rumus D4(p,q,r,s) = |x-s|+|y-t|+|z-u|+|w-v|
A,B
= |1000-870|+|20-7|+|10-29|+|200-148| = 214
A,C =
|1000-1100|+|20-0|+|10-250|+|200-10| = 550
A,D =
|1000-900|+|20-20|+|10-10|+|200-170| = 130
