Answer:

45 cm

Step-by-step explanation:

Mengingat bahwa;

 sisi-sisi segitiga ABC memiliki panjang yang sesuai:

|AB| = 15 cm

|BC| = 12 cm

|AC| = 18 cm

Kita harus menemukan keliling segitiga

Lingkaran segitiga adalah jumlah dari semua sisi segitiga

Begitu;

keliling segitiga ABC = |AB| +  |BC|  +  |AC|

keliling segitiga ABC = 15 cm + 12 cm + 18 cm

keliling segitiga ABC = 45 cm
