2) CA = 25 (pake cara phytagoras)
 *  \frac{ca}{cb}  \frac{ab}{bd}
 =  \frac{25}{24}  \frac{7}{bd}
 = 24 x 7 = 25 x bd 
 = 168 = 25 x bd
 = bd =  \frac{168}{25}
 = 6,75
3)  \frac{ln}{lm}  \frac{ld}{lk}
 =  \frac{12}{24}  \frac{16}{lk}
 = 12 x lk = 24 x 16
 = lk =  \frac{384}{12}
 = 32
 * jadi kd = lk - ld = 32- 16 = 16
