Answer 1

K1 = 2 × (P + L)

K1 = 2 × (48 + 14)

K1 = 2 × 62

K1 = 124 cm

K2 = 2 × S

K2 = 2 × 20

K2 = 40

K1 + K2

124 + 40

= 164 cm

opsi C

Answer 2

K¹ = 2 × ( p + l )

K¹ = 2 × ( 48 + 14 )

K¹ = 2 × ( 62 )

K¹ = 124 cm

_____________

K² = 2 × s

K² = 2 × ( 34 - 14 )

K² = 2 × 20

K² = 40 cm

_______________

k gabungan = k¹ + k²

K gabungan = 124 cm + 40 cm

K gabungan = 164 cm
