<u>Answer-</u>

<u>Solution-</u>
Triangle Midpoint Theorem-
<em>The line segment connecting the midpoints of two sides of a triangle is </em><em>parallel to the third side</em><em> and is congruent to </em><em>one half of the third side</em><em>.</em>
As in the question it is given that,
OQ = MQ, so Q is the mid point of MO,
OP = NP, so P is the mid point of NO.
Hence, PQ is the line joining the midpoints of MO and NO.
Applying Triangle Midpoint Theorem,



Therefore, the length of PQ is 7.2 units.
