keliling = jumlh seluruh sisi nya
keliling = 3 x 3
keliling = 9 cm
---
keliling = 11 + 11 + 8 + 10
keliling = 22 + 18
keliling = 40 cm
keliling = 5 x 3 + 4 x 2
keliling = 15 + 8
keliling = 23 cm
maaf klo slah -.-
Jawaban:
segitiga = 9 cm
trapesium = 40 cm
segi lima = 23 cm
Penjelasan dengan langkah-langkah:
a. segitiga
K = s + s + s
K = (3 + 3 + 3) cm
K = 9 cm
b. trapesium
K = jumlah semua sisi
K = (11 + 10 + 11 + 8) cm
K = 40 cm
c. segi lima
K = (5 + 5 + 5 + 4 + 4) cm
K = 23 cm
