Once upon a time, hidden among the mountains, there was a mysterious village called Polygon Village. In this village, every shape had a story, and every story had to solve a riddle. But one day, after a black fog enveloped the entire village, all the polygons began to forget themselves—their features, their lives, and their purpose

The villagers sought help from a brave young girl named Mary, who lived miles away from the village. Mary arrived at the village and observed her surroundings, trying to understand what was happening. She pondered why the fog had appeared and how it could be dispelled

Suddenly, a giant owl appeared before Mary. This owl had glasses, fluffy feathers, and looked quite stern. The owl walked towards Mary.

Mary asked, 'Who are you?' The owl responded, 'I am the wise guardian and overseer of this village. I monitor the shapes, ensuring they fulfill their responsibilities, and I converse with them accordingly

Mary stared at the owl in astonishment and replied, 'Do you know what's happening here? What is this fog that has caused them to lose their memories?' The owl flew quickly around Mary and perched on her shoulder, gesturing for her to look in the opposite direction

Mary turned to see an even larger fog cloud approaching them. The owl said, 'This fog is a poisonous smoke sent by neighboring villages. They resorted to this method to make the polygons living here forget everything and take over this village.

Mary asked, 'So, what can we do to solve this situation?' The owl replied, 'We can hide the polygons in the mysterious room until the fog disperses. But the door to the room only opens when the polygons reveal their properties and area formulas. It's a very mysterious room, after all.

Mary and the owl quickly made their way to the area where the polygons were gathering. Some couldn't remember any of their properties, while others had already forgotten half of them. Mary climbed to a height and called out to them, 'I want to save you, but you must help me. Now, I will tell you your properties and area formulas, and you will memorize them. Then, you will unlock the code to the mysterious room and hide inside. But we must hurry
