AB= BC/2

AB=CD/3

AD = 24

 

AB = AB

BC/2 = CD/3

BC*3 = CD*2

3BC /2 = C

•-----------•----------•--------------•

A............B...............C...............D

....BC/2..........BC..............3BC/2

 

BC/2 + BC + 3BC/2 = 24

BC/2 + 2BC/2+ 3BC/2 = 24

6BC/2 = 24

3BC = 24

BC =24/3

BC = 8

 

AB = BC/2

AB = 8/2

AB= 4

 

CD = 3BC/2

CD = 3.8/2

CD = 3.4

CD = 12

 

Rta = Ab = 4

 

espero que te sirva, salu2!!!!
