Jawab:
132 cm 2
Penjelasan dengan langkah-langkah:
Segitiga kiri = (a * t) : 2
= (3 * 12) : 2
= 36 : 2
= 18 cm 2
Persegi Panjang = p * l
= 15 * 12
= 180 cm 2
Segitiga Kanan = (a * t) : 2
= (5 * 12) : 2
= 60 : 2
= 30 cm 2
Luas Yang Diarsir = 180 - 30 - 18
= 132 cm 2
Matematika
Luas trapesium
= ½ × ((10+5) + 7) × t
= ½ × (15 + 7) × 12
= 6 × (22)
= 132 cm²
