no 1.rumah beni - taman kolam jarak pada denah 3 cm skala 1:1000,1:1.300,1:2.000 tentukan jarak sesungguhnya dengan skala tersebut ? pakai cara

1 : 1000
Js = S x Jp
Js = 1000 x 3 = 3000 cm
Js = 30 m

1 : 1.300
Js = S x Jp
Js = 1.300 x 3 = 3.900 cm
Js = 39 m

1 : 2.000
Js = S x Jp
Js = 2.000 x 3 = 6.000 cm
Js = 60 m

1:1000 = 3:1/1000 = 3x1000 = 3000 = 30 meter
1:1300 = 3:1/1300 = 3x1300 = 3900 = 39 meter
1:2000 = 3:1/2000 = 3x2000 = 4000 = 40 meter
