Answer 2

Jawaban:

dik = panjang sisi 1 = 4 cm

panjang sisi 2 = 1 cm

panjang sisi 3 = 1,5 cm

dit = keliling = ...?

jawab =

Cara 1 =

K = (4 × 2) + (1,5 × 2) + (1 × 8)

K = 8 + 3 + 8

K = 11 + 8

K = 19 cm

Cara 2 =

K = 4 + 1 + 1 + 1,5 + 1 + 1 + 4 + 1 + 1 + 1,5 + 1 + 1

K = 5 + 1 + 1,5 + 1 + 1 + 4 + 1 + 1 + 1,5 + 1 + 1

K = 6 + 1,5 + 1 + 1 + 4 + 1 + 1 + 1,5 + 1 + 1

K = 7,5 + 1 + 1 + 4 + 1 + 1 + 1,5 + 1 + 1

K = 8,5 + 1 + 4 + 1 + 1 + 1,5 + 1 + 1

K = 9,5 + 4 + 1 + 1 + 1,5 + 1 + 1

K = 13,5 + 1 + 1 + 1,5 + 1 + 1

K = 14,5 + 1 + 1,5 + 1 + 1

K = 15,5 + 1,5 + 1 + 1

K = 17 + 1 + 1

K = 18 + 1

K = 19 cm
