jika setiap satuan mewakili 1 cm maka keliling bangun tersebut adalah​

Jawaban:

B. 36 cm

Penjelasan dengan langkah-langkah:

12) p = 10 cm l = 8 cm

Keliling = 2 x (p+l)

K = 2 x 18

K = 36 cm

12. panjang = 10 satuan

lebar = 7 satuan

kel = 2p + 2l = 2(10) + 2(7)

= 20 + 14

= 34 cm (A)

13. luas ∆ = 1/2 x alas x tinggi

= 1/2 x 6 x 8

= 24 cm² (D)
