    The rule says the perimeter ratio of two ST is the same as the ratio of the length, the area ration is sqare that

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

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

    which means LN/MN=NR/NP
