Answer 1

1) 35/x = 25/15
25.x = 35.15
25.x = 525
x = 525/25
x = 21 cm (C)


2) 12/x = 30/45
30.x = 12.45
30.x = 540
x = 540/30
x = 18 m (D)


3) 1,6/x = 4,8/42
4,8.x = 1,6.42
4,8.x = 67,2
x = 67,2/4,8
x = 14 cm (B)


4) stlah diperbesar ukurannya mnjadi:
p = 4.2 = 8 cm
l = 6.2 = 12 cm
jadi, K = 2.(p+l)
= 2.(8+12)
= 2.20
= 40 cm (C)


5) JP = JS : Skala
