Question

(05.05) On a coordinate plane the coordinates of vertices R and T for a polygon are R(-7, 3) and T(3,3). What is the length of Side RT of the polygon?
4 units
6 unts
10 units
15 units
PLEASE HELP!!

Answer 1

Answer:

c) 10 units

The length of side RT of the polygon  RT = 10

Step-by-step explanation:

Step(i):-

Given the coordinates of vertices R and T

R( -7 ,3) and T (3 ,3)

we have to find the length of side RT

We will use distance formula

RT  = $\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }$

Step(ii):-

RT  $= \sqrt{(3-3)^{2} +(3-(-7))^{2} }$

$RT = \sqrt{0+(10)^{2} }$

RT = √100

RT = 10

The length of side RT of the polygon  RT = 10
