Jika panjang KL= 46 cm dan MN= 22 cm, maka keliling trapesium KLMN adalah...

sisi miring pada trapesium
s² = 16² + 12²
s² = 400
s = 20 cm

keliling trapesium KLMN
= 20 + 20 + 46 + 22
= 108 cm

46-22 = 24 cm
NM = 22 cm
KL = 46 cm
NP = 16 cm
KP = 24:2 = 12cm
Ptytagoras
KN kuadrat = KP kuadrat + NP kuadrat = 12cm kuadrat + 16cm kuadrat= 144 + 256 = √400 = 20cm
ML = KN = 20 cm
Keliling = NM + ML + LK + KN = 22cm + 20 cm + 46cm + 20 cm = 108 cm

Semoga bermanfaat
