Answer: The approximate length of PQ is 10.8 unit.

Explanation:

Here the coordinates of point P are (-3,7) and the coordinates of Q are (6,1)

Thus, by the distance formula,

The distance between the points P and Q is,

PQ = √((6-(-3))^2+(1-7)^2)

$=\sqrt{(6+3)^2+(-6)^2$

=√(9^2+ 36)

$=√(81+36)=√(117)=10.8166538264\approx 10.8$

Thus, the approximate length of PQ is 10.8 unit.
