# Calculate the length of each side of the triangle
side1 = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)
side2 = math.sqrt((x3 - x2)**2 + (y3 - y2)**2)
side3 = math.sqrt((x1 - x3)**2 + (y1 - y3)**2)


# Calculate the perimeter of the triangle
perimeter = side1 + side2 + side3

# Print the perimeter
print(f"The perimeter of the triangle is: {perimeter:.2f} units.")
