Luas sebenarnya=(psbnrnyaxlsbnrnya)=(6x500)x(3x500)=3000x1500=450m²Verified answer
MAPEL = MATEMATIKAKELAS = 5
BAB = SKALA
diketahui :
- panjang denah (Pd)= 1cm + 2cm = 3cm
- lebar denah (Ld) = 1cm + 3cm + 2cm = 6cm
- skala = 1 : 500 ➡ 1/500
ditanya = luas sebenarnya??
- panjang sebenarnya ( PS ) :
skala = Pd/PS
1/500 = 3cm/PS
PS = 500 × 3cm
PS = 1500cm ➡ 15m
- lebar sebenarnya (LS) :
skala = Ld/LS
1/500 = 6cm/LS
LS = 500 × 6cm
LS = 3000cm ➡ 30m
luas sebenarnya = P × L
= 15m × 130m
= 450m²
semoga membantu
