Total length of the trim painted is 15.75 unit.
Given:
- Co-ordinate of point A = (-2,4)
- Co-ordinate of point B = (2,2)
- Co-ordinate of point C = (-1,-2)
Find:
Total length of the trim painted
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between AB = √(-2 - 2)² + (4 - 2)²
Distance between AB = √16 + 4
Distance between AB = 2√5 unit = 4.47 unit
Distance between BC = √(2 + 1)² + (2 + 2)²
Distance between BC = √9 + 16
Distance between BC = 5 unit
Distance between AC = √(-2 + 1)² + (4 + 2)²
Distance between AC = √1 + 36
Distance between AC = √37 unit = 6.08 unit
Total length of the trim painted = 4.47 + 5 + 6.08
Total length of the trim painted = 15.75 unit (Approx.)
