Question

Find the perimeter of the triangle whose vertices are the following specified points in the plane. (−2,−8),(−7,9) and (2,−5)

Answer 1

39.36

Explanation:

Calculate the distance between (2, -5) & (-7, 9), (-7, 9) & (-2, -8) and (-2, -8) & (2, -5). Then add the sum of all 3 numbers together and that's the perimeter.

`√(277) +√(314) +5=39.36`
