Penjelasan dengan langkah-langkah:
1. luas 2 persegi panjang = ( p × l ) + ( p × l )
= (90 cm × 10 cm) + (60 cm × 14 cm)
= 900 cm² + 840 cm²
= 1740 cm²
2. keliling = [2 × (p + l) ] + [2 × (p + l) ]
= [ 2 × (24 cm + 5 cm) ] + [ 2 × (14 cm + 3 cm) ]
= (2 × 29 cm) + (2 × 17 cm)
= 58 cm + 34 cm
= 92 cm
3. luas = luas 1 + luas 2 + luas 3
= (p × l) + (p × l) + (p × l)
= (3 cm × 5 cm) + (3 cm × 5 cm) + (12 cm × 4 cm)
= 15 cm² + 15 cm² + 48 cm²
= 78 cm²
