The sides of a triangle are in the ratio of 1/2:1/3:1/4. if the perimeter is 52cm, the length of the smallest side is​?

  One side is     1/2  out of  (1/2 + 1/3 + 1/4)   =   1/2 out of  13/12

 

1/2 / (13/12)    * 52  = 24 cm

 

second side is   1/3 / (13/12) * 52 = 16 cm

 

 

You can multiply out for the third side or just subtract the first two sides above from 52 to find the third side...
