Question

On a coordinate grid the coordinates of vertices p and q for polygon pars are p(5,4) and q(-2,4) what is the length of side pq?

Answer 1

pq = 7

Explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = p(5, 4) and (x₂, y₂ ) = q(- 2, 4)

pq =
`√((-2-5)^2+(4-4)^2)`

=
`√((-7)^2+0^2)`

=
`√(49)`

= 7
