Пятиугольник - это геометрическая фигура с пятью углами.
Пятиугольники бывают правильные ( все стороны и углы равны)
и неправильные ( стороны и углы не равны).
Начерти любой , измерь его стороны.
Периметр - сумма длина всех сторон.
Правильный пятиугольник:
Р= 5* а , где а - длина стороны
Неправильный пятиугольник:
Р= а+b+c+d+e , где а,b,с,d,е - длина каждой стороны
Всё просто.

  Once there was a king, who liked to paint pictures, but his

pictures were bad and nobody liked them. The people to whom the king showed his pictures were afraid of him and they said that the pictures were good. One day the king showed his pictures to a great painter who lived in that country and said, “What do you think of my pictures? Am I a good painter or not?” The painter looked at the king’s picture and said, “My king, the pictures are bad and you will never be a good painter.” The king was very angry and sent the painter to prison. After two years the king wanted to see the painter again. When the painter came the king gave him a good dinner and said, “Now you are a freeman and I am your friend.” So he talked kindly to the painter.
