Ok, let's get the rule sorted first

  • caozeyuan
The rule says the perimeter ratio of two ST is the same as the ratio of the length, the area ration is sqare that
caozeyuan
  • caozeyuan
so your last Q said the ratio of length is 3:4, so perimeter ratio is 3/4 and area is 9/16

For this Q, you have to understnad one thing: the similar notation has to be written so that the two triangles corresponds

  • caozeyuan
In the context of your Q, LNR and MNP are similar, meaning that LN corresponds to MN and NR corresponds to NP
caozeyuan
  • caozeyuan
which means LN/MN=NR/NP

  • caozeyuan
now you have the equation and you can solve!
