Question : In a $\triangle$LMN, OP is a line segment drawn parallel to the side MN. OP intersects the sides LM and LN at O and P, respectively. If LM = 15 cm, OM = 4 cm, and PN = 5 cm, then what is the length (in cm) of the side LN?
Option 1: 16.25
Option 2: 18.75
Option 3: 20.25
Option 4: 22.75
Correct Answer: 18.75
Solution : OP || MN LM = 15 cm OM = 4 cm PN = 5 cm LO = LM – OM = 15 – 4 = 11 cm Let LN = $x$ cm LP = LN – PN = $(x-5)$ cm In $\triangle LOP$ and $\triangle
