Пошаговое объяснение:

1) тк угол М= углу N, то треугольник MNK-равнобедренный, следовательно КМ=КN.

2) тк КМ=КN, MR=MN, то KN+MR=KN+MR.

3) P=KM+MR+KN+RN=2×(KM+MR)=2×25=50.

The Legendary Quest: A Gamer’s Journey.
Once upon a time, in the small town of Gamerland, there lived a young boy named Alex. Alex was an avid fan of computer games and had always dreamt of becoming a professional gamer one day. His room was filled with posters of his favorite game characters, and he spent hours honing his skills on his computer. One day, Alex stumbled upon a mysterious old book in his attic. The book had a worn-out cover and was titled "The Legendary Quest: A Gamer's Journey." Curiosity sparked within Alex, and he decided to open the book and explore its contents. As he flipped through the pages, a blinding light engulfed him, transporting him into a virtual world known as Gameoria. Alex found himself standing in the middle of a vibrant and fantastical landscape. It was a world where computer games came to life, and players could interact with their favorite characters and embark on thrilling adventures. Excited about his newfound adventure, Alex encountered a friendly NPC named Ruby who guided him through the realm of Gameoria. Ruby explained that to return to the real world, Alex had to complete various gaming challenges and gather legendary artifacts scattered across different game realms. As Alex embarked on his quest, he faced numerous challenges and encountered iconic game characters such as Max the Brave Swordsman, Lara the Clever Explorer, and Zara the Wise Mage. Each character tested his gaming skills and provided valuable insights to aid him on his journey. After overcoming various challenges, Alex finally gathered all the legendary artifacts. He returned to the central plaza of Gameoria, where he encountered the Game Master, an enigmatic figure who watched over the realm. With great anticipation, Alex approached the Game Master, who congratulated him on his success.
