Read three point floating values (A, B and C) and verify if is possible to make a triangle with them. If it is possible, calculate the perimeter of the triangle and print the message:

Perimetro = XX.X

If it is not possible, calculate the area of the trapezium which basis A and B and C as height, and print the message:

Area = XX.X

The input file has tree floating point numbers.

Print the result with one digit after the decimal point.

Input Sample | Output Sample |

6.0 4.0 2.0 |
Area = 10.0 |

6.0 4.0 2.1 |
Perimetro = 12.1 |
