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?
+37146 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...
