Jose wants to find the perimeter of triangle ABC. He uses the distance formula to determine the length of AC. Finish Jose’s calculations to find the length of AC.

AC=square root<(-2-3)^2 +(6-2)
=square root<(-5)^2+(4)^2

What is the perimeter of triangle ABC? Round the answer to the nearest tenth, if necessary

Given:
AC = √(-2-3)² + (6-2)²
AC = √ -5² + 4²
AC = √ 25 + 16
AC = √41
AC = 6.40

I am assuming that the triangle is an equilateral triangle. This means that all sides are equal.

AC = AB = BC

Perimeter = 6.40 * 3 sides = 19.20
Edufirst
AC = √[(-2-3)^2 + (6-2)^] = √[5^2 + 4^2] = √[25+16] = √41 =6.4

To find the perimeter you need the lengths of AB and BC.

You already know the points (-2,6) and (3,2)

Then you need the point B to apply the distance formula from B to each of those points.
