The coordinates of the vertices of △pqr are p(2,−1), q(4,2), and r(6,0). identify the perimeter of △pqr. round each side length to the nearest tenth before adding.

The perimeter of △pqr is 10.5

Explanation

The coordinates of the vertices of △pqr are p(2,−1), q(4,2), and r(6,0)

First we need to find the length of each side of the triangle using distance formula between two points.

The length of  pq ,

the length of qr

and the length of pr

As the perimeter means the sum of all sides, so the perimeter

false
