Автор ответа: мариника

чем меньше разница между длиной и шириной, тем меньше периметр, минимальный периметр при одной и той же площади получается, если

длина равна ширине т.е надо извлечь корень из 2500= 50 м длина и 50 м - ширина

(50+50)*2=50*4=200 м сетки рабицы понадобится

Safety on the School Bus

Every year, children are injured because they have not learned a few basic rules about school bus safety. Many people believe that children are most often hurt while they are on the school bus. However, this is not true. Most accidents take place when the child is outside the bus, not inside. Of course, some injures occur because of crashes, but most of them happen when children are in the blind spots around the bus; they occur when the children are hidden from the driver’s view.

To avoid accidents, children should learn to obey a few simple rules. Firstly, they should always keep a safe distance between themselves and the tyres or rear of the bus. Secondly, in cases where children need to cross the road when they get off the bus, they should walk at least three metres in front of the bus and then wait for the driver to signal to them that it is safe to cross the other side of the roadway. In addition, when waiting for their bus to arrive, children should stand well away from the road. Finally, they should never try to get on or off the bus until it has come to a complete stop and the driver has opened the door.
