Find the perimeter of the triangle whose vertices are the following specified points in the plane (-2,-7) (1,-6) and (-7,7)

Answer 1

I assume you know how to find the distance between two points.

I will do the first length, you do the rest.

from (-2,-7) to (1,-6)
distance = √( (-2-1)^2 + (-7+6)^2 )
= √( 9 + 1)
= √10

after finding the other two, add them up

Answer 2

fi
nd the perimeter of the triangle whose vertices are the following specified points in the plane.
(−10, −3), (7, 4)
and
(−1, 7)
