Answer: 11 units
Step-by-step explanation:
Given: On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(5, 2).
To find : length of Side RT of the polygon.
Using distance formula to find distance between (a,b) and (c,d):
[tex]d=\sqrt{(d-b)^2+(c-a)^2}[/tex]
Length of RT = [tex]\sqrt{(2-2)^2+(5-(-6))^2}[/tex]
[tex]\\\\=\sqrt{0+(5+6)^2}\\\\= \sqrt{11^2}\\\\=11[/tex]
hence, the length of RT = 11 units.
