Tolong bantu ya pakai cara

1. Jp = Js : skala
= 112m : 525cm
= 112x100= 11200cm : 525cm
= 21,3cm

2. P = k : 4
= 460 : 4
= 115m

Jp = Js : skala
= 115x100= 11500cm : 375cm
= 30,7cm

3. P = k : 4
= 0,48 : 4
= 0,12hm

Skala = Js : Jp
= 0,12x10.000=12000 : 8
= 1500cm = 1 : 1500cm

4. Jp = Js : skala
= 2,4 x 1,5hm : 600
= 2,4 × 10.000 1,5 × 10.000 : 600
= 24.000 × 15.000 : 600
= 40 × 25cm

5. P =
[tex] \sqrt{28.900} = 170m[/tex]

K = 4 x p
= 4 x 170
= 680m

Jp = Js : Skala
= 680x100=68.000 : 3.400
= 20cm
