Soal Soal Soal​

K persegi

K = 4s

K = 4 × 8 cm

K = 32 cm

-

K segitiga

K = a + b + c

K = 8 cm + 10 cm + 10 cm

K = 18 cm + 10 cm

K = 28 cm

-

K gabungan

K = persegi + segitiga

K = 32 cm + 28 cm

K = 60 cm

#koreksi

Segitiga

Diketahui :

sisi = 10 cm

Ditanya :

keliling ... ?

Jawaban :

kll = a + b + c
