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
