Triangle

Adapted by Neilor Tonin, URI Brazil

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

Input

The input file has tree floating point numbers.

Output

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

N.B.: It's better if you solve this by your own. Thank you!
