The length of line segment OM is 34 cm.

<u>Step-by-step explanation</u>:

The diagonals of a parallelogram bisect each other (cuts equally into two halves).
The line segment OM is a diagonal with an intersection point Q.
The line segment OQ is equal in length as the line segment QM.

Step 1 :

⇒ length of OQ = length of QM

⇒ 2x + 3 = 3x -4

⇒ 3x-2x =4+3

⇒ x = 7

Step 2 :

Subsitute x = 7 in OQ and QM

⇒ length of OQ = 2x+3

⇒ 2(7) + 3 = 17 cm

⇒ length of QM = 3x-4

⇒ 3(7) - 4 = 17 cm

∴ Length of OM = length of OQ + length of QM
