Point N is marked on segment CD. Find the length of segment CD if segment CN = 45 cm, and segment ND is shorter than segment CN by n cm. Simplify the resulting expression and find its value at n = 36.

If CN is 45, and ND is shorter than CN by n cm, then it means that ND is 45-n, that is, 45-36 = 9
So ND is 9
CD consists of ND and CD, so add 45 and 9, we get 54
