Question 758150

Find the perimeter of triangle ABC, with coordinates A(-3, 0), B(0, 4), and C(3, 0)


Using distance formula: {{{d = sqrt((x[2] - x[1])^2 + (y[2] - y[1]))}}}, you will get AB = 5 units, and BC = 5 units.


Since A and C have the same y-coordinate (0), these two points will be on the x-axis where all y-values are 0. Therefore, AC will have a length of 3 - - 3, or 6 units.


Perimeter = 5 + 5 + 6, or {{{highlight_green(16)}}} units
