tlong bantu jwb y mksih

MAPEL = MATEMATIKA
KELAS = 5
BAB = SKALA

diketahui :
- panjang denah (Pd) = 1cm + 1cm + 1cm = 3cm
- lebar denah (Ld) = 1cm + 1,5cm + 1,5cm + 1cm = 5cm
- skala = 1 : 300 ➡ 1/300

ditanya = luas sebenarnya ??

- panjang sebenarnya ( PS )
skala = Pd/PS
1/300 = 3cm/PS
PS = 300 × 3cm
PS = 900cm ➡ 9m

- Lebar sebenarnya ( LS )
skala = Ld/LS
1/300 = 5cm/LS
LS = 300 × 5cm
LS = 1500cm ➡ 15m

luas sebenarnya = P × L
= 9m × 15m
= 135m²

jawaban D.
semoga membantu
