Answer:
7 units
Step-by-step explanation:
Use distance formula between two points [tex]A(x_A,y_A)[/tex] and [tex]B(x_B,y_B):[/tex]
[tex]AB=\sqrt{(x_A-x_B)^2+(y_A-y_B)^2}[/tex]
On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(1, 2). Then the length of the side RT is
[tex]RT=\sqrt{(-6-1)^2+(2-2)^2}=\sqrt{(-7)^2+0^2}=\sqrt{49}=7\ units[/tex]
