1) Lk = p × l
= 120 × 80
= 9600 cm²
Llyg2 = ½ × d1 × d2
= ½ × 45 × 30
= 675 cm²
sisa kertas = 9600 - 675 = 8925 cm²

2) Lk = p × l
= 8 × 6
= 48 m²
Lkolam = s²
= 4 × 4
= 16 m²
L sisa = 48 - 16 = 32 m²

3) Lk = s²
= 75 × 75
= 5625 cm²
Llngkran = 24 × 3,14 × 4 × 4
= 1205,76 cm²
Luas sisa = 5625 - 1205,76 = 4419,24 cm²
