Jawaban:
= 172 cm²
Penjelasan dengan langkah-langkah:
= persegi panjang 1 + persegi panjang 2
= p × l + p × l
= 7 × 4 + 8 × 18
= 28 cm² + 144 cm²
= 172 cm²

SOAL 1
L Persegi Panjang 1 = P × L
L Persegi Panjang 1 = 11 × 8
L Persegi Panjang 1 = 88 cm²
L Persegi Panjang 2 = P × L
L Persegi Panjang 2 = 12 × 7
L Persegi Panjang 2 = 84 cm²
Luas = L Persegi Panjang 1 + L Persegi Panjang 2
Luas = 88 + 84
Luas = 172 cm²
