answer: 3.21 x 10^8
short answer no they are not congruent. the scale factor would be 1 if they were. jl and rt should both be the same length (they are opposite angles marked with 2 quarter circles). they are not equal. so the scale factor is not 1.
to get from jkl to rst you must multiply every length of jkl by = 20 / 25 or 4/5. so 15 * 4/5 = 12 which works. 4/5 * 20 = 16 which also works.
the two triangles are similar.
