Triangles JNM and MNL are similar triangles.

(1) Use the Pythagorean Theorem to find the length of JN. (Or you might recognize the lengths of MN and JM as being part of a Pythagorean triple, which means you won't need to use the Pythagorean Theorem.)

(2) Use the two similar triangles to find the length of NL.

(3) The length you need to find is the sum of the lengths of JN and NL.
