Jawab:

bangun datar

trapesium sama kaki

pada  gambar trapesium  KLMN
KO =  1/2 (KL – MN)
KO = 1/2 (14 -8)
KO = 1/2 (6)
KO =  3

a)  jarak N ke KL = NO

ΔKON siku di O
NO² = KN²- KO²
NO² =  5² – 3² = 16
NO =  4 cm

b. jarak  O ke M = diagonal
OM² =  MN²+ NO²
OM² = 8² +  4² = 64 + 16 =  80
OM = √80
OM = 4√5 cm
