The equation that can be used to find the proportion to use to solve side LM is 9/13.5 = 14/LM
Similarity theorem of triangle
In order to find the measure of LM, we will take the ratio of the sides of the similar triangles.
Using the equation as shown
DF/EF = LK/LM
DF/LK = EF/LM
Substitute the measure of the sides
9/13.5 = 14/LM
Hence the equation that can be used to find the proportion to use to solve side LM is 9/13.5 = 14/LM
