panjang sebenarnya :
= 18 cm × 500
= 9.000 cm (÷100)
= 90 m
lebar sebenarnya :
= 12 cm × 500
= 6.000 cm (÷100)
= 60 m
Keliling :
= 2( p + l )
= 2(90 + 60)
= 2(150)
= 300 m
Luas :
= p × l
= 90 × 60
= 5400 m²
= 18 cm x 500 = 9.000 cm = 90 m
lebar sebenarnya
= 12 cm x 500 = 6.000 cm = 60 m
Keliling Sebenarnya
= 2 (90 m + 60 m)
= 2 (150 m)
= 300 m
Luas Sebenarnya
= 90 m x 60 m
= 5.400 m²
