Penjelasan dengan langkah-langkah:
12. K = 4 x s = 4 x 13 = 52 cm
L = 1/2 x d₁ x d₂
= 1/2 x 10 x d₂
1/2 d₂ = cm
d₂ = 12 x 2 = 24 cm
L = 1/2 x 10 x d₂
= 1/2 x 10 x 24
= 120 cm²
Catatan: 1/2 d₂ = jarak dari titik tengah ke ujung kanan/kiri
13. K = 4 x s
s = cm
K = 4 x s = 4 x 15 = 60 cm
= 1/2 x 18 x 24
= 216 cm²
