The distance between any 2 points P(a,b) and Q(c,d) in the coordinate plane, is given by the formula:
[tex]|PQ|= \sqrt{ (a-c)^{2} + (b-d)^{2} }[/tex]
Thus, the distance between points (3,2) and (2,0) is:
[tex]d= \sqrt{ (3-2)^{2} + (2-0)^{2}}=\sqrt{1 + 4}= \sqrt{5} [/tex]
Answer: [tex]\sqrt{5}[/tex] units
