kak tolong bantu ya.. no 33-35

33. lF = 12-3-3 = 6 cm
pF = 20/12 x 6 = 10 cm
lbf = 20-10-3 = 7 cm ( C )

34. 12/(12+9) = EF/24,5
EF = 24,5 x 12/21 = 24,5 x 4/7 = 14 cm
FG = 24,5 - 14 = 10,5 cm ( B )

35. BD = √13²-5² = √169-25 = √144 = 12 cm
BD = √AD x CD
AD = BD²/CD = 12²/5 = 144/5 = 28,8 cm ( A )
