## anonymous one year ago On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(5, 2). What is the length of Side RT of the polygon? I need help on this im bad at area. 4 6 7 11

You simply calculate the distance between coordinates R and T, like this: $r = \sqrt{(-6-5)^2 + (2-2)^2} = \sqrt{11^2} = 11$
