Ok, let's get the rule sorted first

caozeyuan · Answer

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 · Answer

so your last Q said the ratio of length is 3:4, so perimeter ratio is 3/4 and area is 9/16

caozeyuan · Answer

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

caozeyuan · Answer

In the context of your Q, LNR and MNP are similar, meaning that LN corresponds to MN and NR corresponds to NP

caozeyuan · Answer

which means LN/MN=NR/NP

caozeyuan · Answer

now you have the equation and you can solve!
