Jawaban:
D. 1.988 cm²
Penjelasan dengan langkah-langkah:
L1 = P x l
= 38 x 46 = 1.748 cm²
L2 = P x l
P = 20 cm
l = 38 – 14 – 12 = 12 cm
L= 20 x 12 = 240 cm²
Ltotal = 1.748 cm² + 240 cm² = 1.988 cm²
D. 1.988 cm²

● Luas Persegi Panjang Besar
= p × l
= 46 × 38
= 1.748 cm²
● Luas Persegi Panjang Kecil
= p × l
= 20 × 12
= 240 cm²
● Luas Bangun Datar
= 1.748 cm² + 240 cm²
= 1.988 cm²
