Ok kakak bantu jawab ya..........
i) 8/a = 9/(9 + 3)
8/a = 9/12
8/a = 3/4
a = ( 8 x 4)/3
= 32/3
= 10 2⁄3 cm
ii) b/14 = 12/(12+9)
b/14 = 12/21
b/14 = 4/7
b = (14 x 4)/7
b = 8 cm
iii) 10/15 = 12/(12+c)
2/3 = 12/(12 + c)
24 + 2c = 36 (dikali silang)
2c = 36 - 24
2c = 12
c = 12/2
c = 6 cm
iv) 18/24 = d/(d+12)
3/4 = d/(d + 12)
4d = 3d + 36 (dikali silang)
4d - 3d = 36
d = 36 cm
