Answer: 11 units

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):

d=√((d-b)^2+(c-a)^2)

Length of RT =
√((2-2)^2+(5-(-6))^2)

$\\\\=√(0+(5+6)^2)\\\\= √(11^2)\\\\=11$

hence, the length of RT = 11 units.
