Нехай периметри трикутників ABC і ABD дорівнюють відповідно P1 і P2. Тоді, оскільки медіана BD ділить периметр трикутника ABC на дві рівні частини, то P1 = P2/2.

Таким чином, P1 = 36/2 = 18 см.

Отже, периметр трикутника ABC дорівнює P1 + P2 = 18 + 36 = 54 см.

Відповідь: 54 см.

Chinese Food - What a Way to Cook! My interest in Chinese food started many years ago, when I had my first job. I was a young reporter for the Daily Journal in San Francisco. Our office wasn't far from China town. I usually managed to arrange my schedule so that I could go there at least two or three times a week for a good meal. The first time I ever ate Chinese food I loved it. And since then, it just tastes better and better tome. The first thing I loved I noticed was the fresh taste of the meat and vegetables. When I learned more about the food. I began to understand why it has this unique feature. About 5000 years ago, China lost much of its wood because of overpopulation and poor management of its forests. This loss was very bad for the country of course, but it turned out to be very good for the food. Wood became very expensive and hard to get, so the Chinese had to either find a substitute for their valuable, so people found ways to economize. In order to economize in cooking they had to use very little wood. So they started cutting their meat and vegetables into small pieces before they put them in the hot oil. That way, the food cooked faster and they saved their fuel. The food prepared in this manner kept its fresh flavor-and it's that flavor that attracts people to the art of Chinese cooking. I often wonder if the Chinese appreciated their solution to that ancient energy crisis as much as I do now-whenever I eat Chinese food. -Pete Maxwell. Staff Writer 1.
