Diketahui :

- Persegi Panjang :
• Lebar (l) : 28 cm
• Panjang (p) : 42 cm

- Layang - Layang :
• Diagonal I (d1) : 28 cm
• Diagonal II (d2) : 42 cm

Ditanya :
- Luas Yg Di Arsir (LA)

LPP = p x l
LPP = 28 x 42
LPP = 1176 cm²

LL = ½ x d1 x d2
LL = ½ x 28 x 42
LL = 14 x 42
LL = 588 cm²

LA = 1176 - 588
LA = 588 cm²

Jawaban : 588 cm²
