And two boys standing in front of a huge, solid glass, the window of the deli, he began uncontrollably laughing, pushing each other in the ribs with elbows, but involuntarily dancing from the brutal cold. They have more than five minutes stuck in front of this magnificent exhibition, to excite the same degree their minds and stomachs. Here, lit by the bright light of hanging lamps, stood a whole mountain of red sturdy apples and oranges; the right stood the pyramids of tangerines, gently zolotuchina through wrapping them in tissue paper; stretches for the dishes, ugly open-mouthed and eyes bulging, huge smoked and marinated fish; below, surrounded by garlands of sausages, adorned with juicy sliced ham with a thick layer of pinkish fat... Countless cans and boxes with salt, boiled and smoked meats completed this spectacular picture, which is looking at both boys for a moment forgot about dvenadtsatikolonnom the cold and about the important task assigned to them by the mother — order, which ended so suddenly and so badly.The older boy first broke away from the contemplation of the charming spectacle. He pulled brother's sleeve and said sternly:— Well, Volodya, come on, come on... there is Nothing...At the same time suppressing a heavy sigh (the eldest of them was only ten years old, and also both in the morning nothing to eat but empty soup) and throwing the last with love the greedy look on the gastronomic exhibition, the boys quickly ran down the street. Sometimes through the steamed-up Windows of any house they saw the tree, which from a distance seemed like a huge bunch of bright, shining spots, sometimes they even heard the sound of cheerful polka... But they bravely drove away the tempting thought to stay for a few seconds and stick the eye to the glass.
В задаче не сказано какой формы будут клумбы - вот и задумался садовник. Рисунок к задаче в приложении.
Если стороны равны - а , то это ромб или квадрат. Тогда периметр по формуле: Р = 4*а.
Если стороны разные: a и b, то это параллелограмм или прямоугольник и периметр по формуле: P = 2*(a + b).
1) а = b = 4 м. Р1 = 4*а = 4*4 = 16 м - периметр первой клумбы.
2) Р2 = 2*(6 + 4) = 2*10 = 20 м - периметр второй клумбы
3) Р3 = 2*(7 + 2) = 2*9 = 18 м - периметр третьей клумбы.
4) Р4 = 2*(5 + 3) = 2*8 = 16 м - периметр четвёртой клумбы.
И теперь длину изгороди на все четыре клумбы - сумма отдельных.
5) Р = 16+20+18+16 = 70 м на все четыре клумбы - ОТВЕТ
