Pembahasan :

Diketahui :

- Persegi Panjang :
• Panjang (p) : 20 cm
• Lebar (l) : 14 cm

- ½ Lingkaran :
• 2 Buah
• Diameter (d) : 14 cm
• Jari - Jari (r) : 14/2 : 7 cm

Ditanya :
- Luas Total (LT)

- Cara :

• Luas Persegi Panjang (LPP) :

LPP = p x l
LPP = 20 x 14
LPP = 280 cm²

• Luas 2 ½ Lingkaran (LL) :

LL = π x r²
LL = 22/7 x 7 x 7
LL = 22 x 7
LL = 154 cm²

• Luas Total (LT) :

280 + 154
= 434 cm²

Jawaban : C
