input: def find_triangle_area(x, y, z):
      '''
      Given the side lengths of a triangle. Return the area of the triangle rounded
      to two decimal places if the sides constitute a valid triangle. Otherwise, return -1.
      A triangle is valid if the sum of any two sides is greater than the remaining side.
      Example:
      find_triangle_area(3, 4, 5) == 6.00
      find_triangle_area(1, 2, 10) == -1
      '''
output:     # Check if the given side lengths can form a valid triangle
      if x + y <= z or x + z <= y or y + z <= x:
          return -1
      # Calculate the area using Heron's formula
      s = (x + y + z) / 2
      area = (s * (s - x) * (s - y) * (s - z)) ** 0.5
      # Return the area rounded to two decimal places
      return round(area, 2)
