Answer 1

6) DB / AB = ED / AC
x / x+2 = 6 / 8
8x = 6x + 12
2x = 12
x = 6 cm (b)

7) a

8) DP / AD = CQ / CB
5 / 9 = CQ / 13.5
9CQ = 67.5
CQ = 7.5 cm (d)

9) 6 / 2 = x / 145
870 = 2x
x = 435 cm
x = 4.35 m (d)

10) 4 / x = 3 / 9
36 = 3x
x = 12 cm
L setelah diperbesar = 12 × 9 = 108 cm2 (a)

semoga membantu.
