Jawaban:
Maaf kalau salah
LPP = 2 × luas alas + luas selubung
s = √(d1² + d2²) / 2
s = √(12² + 16²) / 2
s = √(144 + 256) / 2
s = √400 / 2
s = 10 cm
luas alas = luas belah ketupat
luas alas = 1/2 × d1 × d2
luas alas = 1/2 × 12 cm × 16 cm
luas alas = 96 cm²
luas selubung = keliling alas × tinggi
luas selubung = 4 × s × tinggi
luas selubung = 4 × 10 cm × 18 cm
luas selubung = 720 cm²
LPP = 2 × 96 cm² + 720 cm²
LPP = 192 cm² + 720 cm²
LPP = 912 cm²
