    * One coordinate per line - total 8 coordinates
    * Validates if the input coordinates indeed make a square. 
    * In case the coordinates are wrong, program prints "Invalid input" without quotes and trailing newline and exits
    * If input was valid, print perimeter of the square followed by a single space followed by area of the square.
    * Perimeter and area should have two decimal points
    * There should be no trailing whitespace or newline on the output line
