B(5, 1)
C(- 4, - 3)
We would calculate the distance between each vertex by applying the formula for calculating distance between 2 points. It is expressed as
The perimeter of the triangle is the sum of the length of each side. Thus,
Perimeter = 7.81 + 9.85 + 9.49
Perimeter = The perimeter of the triangle is the sum of the length of each side. Thus,
Perimeter = 27.15
