Question

On a coordinate grid, the coordinates of vertices P and Q for Polygon PQRS are P(1, 2) and Q(−1, 2). What is the length of Side PQ of the polygon?

2 units

3 units

4 units

6 units

Answer 1

What do you think?

Answer 2

i really odont know because it dont show a graph

Answer 3

actually i thing A

Answer 4

You have to find the distance between the two points

Answer 5

\( \Large\text{Distance} = \sqrt{ (\color{cyan}{x_2} -\color{red}{x_1})^2 + (\color{green}{y_2} - \color{orange}{y_1)}^2 } \)

where you have two points
\(\Large (\color{red}{x_1}, \color{orange}{y_1})\) and \(\Large (\color{cyan}{x_2}, \color{green}{y_2})\)

So your two points are

\((\color{red}{1}, \color{orange}{2})\) and \((\color{cyan}{-1}, \color{green}{2})\)
