Answer:
[tex]7.21\ units[/tex]
Step-by-step explanation:
Start by giving the points coordinate points assuming the origin is the bottom left:
[tex]A(4,2)\\B(10,6)[/tex]
Apply the formula for the distance between two points:
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]d = \sqrt{(10-4)^2+(6-2)^2}[/tex]
[tex]d = \sqrt{6^2+4^2}[/tex]
[tex]d = \sqrt{36+16}[/tex]
[tex]d = \sqrt{52}[/tex]
[tex]d = 7.21\ units[/tex]
