Similar triangles are tingles with similar shape but can have different sizes.
Since there is something common about them then to establish this relationship we have something called linear scale factor which is used to get the length of the other when the length of the other similar triangle is known.
LSF=30/18=5/3
BC/EF=5/3
9/EF=5/3
EF=5.4cm
