Question

(05.05)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? 4 unit 6 units 7 units 11 units

Answer 1

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):

$d=\sqrt{(d-b)^2+(c-a)^2}$

Length of RT = $\sqrt{(2-2)^2+(5-(-6))^2}$

$\\\\=\sqrt{0+(5+6)^2}\\\\= \sqrt{11^2}\\\\=11$

hence, the length of RT = 11 units.
