Because there is no such thing as the "length of a point", I will assume that you want the length of the line segment joining the points #(-3, -3)# and #(3/2, 7/2)#.

Use the distance formula (the Pythagorean Theorem) to get:

#d=sqrt((3/2-(-3))^2+(7/2-(-3))^2#, so

#d=sqrt( (9/2)^2+(13/2)^2) =sqrt((81+169)/4) = sqrt (250/4)=(5sqrt10)/2#
