338. The Cucumber River, flowing through the Flower City, has several islands in the harbor area, the total perimeter of which is 8 meters. Know-it-all claims that it is possible to set off in a boat from the harbor and cross to the other bank, traveling less than 3 meters. The banks of the river in the harbor area are parallel, and the width of the river is 1 meter. Is Know-it-all right?
338. Answer: Know-it-all is right. The total length of the projections of the islands onto the shore is less than 4 m. Therefore, the distance from the pier to the nearest gap between the islands is less than $2 \mathrm{m}$.
