Ответ: P=102см

S=578см в квадрате

Пошаговое объяснение: Ну вот смотри: у тебя есть ширина прямоугольника 17см, а если длина вдвое больше то умножаешь на два, значит получаем длину в 34см

Чтобы найти периметр надо сложить все стороны(т.е. две ширины и две длины), значит 34+34+17+17=102см. Это мы нашли периметр

Чтобы найти площадь нужно ширину и длину этого прямоугольника умножить на самих себя, значит 34*17=578см(и над словом см ставишь маленькую двоечку)

Автор ответа: Kristya196

1) 17*2=34 (см) - длина прямоугольника

2) (34+17)*2=102 (см) - периметр прямоугольника

3) 34*17=578 (см²) - площадь прямоугольника

HOW THE PAINTER REMBRANDT WAS DISCOVERED
In a museum in Holland one can see a pair of wooden shoes with funny little figures of animals drawn on them. Those drawings led to discovery of the great painter Rembrandt. When he was still a boy, he dreamt of becoming a painter and travelling widely in foreign countries, and he worked to become an artist. One day at school, instead of listening to the teacher's explanation, he was drawing pigs, chickens, other animals and birds on the wooden shoes of the pupil sitting next to him. Seeing this, the teacher got angry with him and said he would tell his parents about his behaviour at school. In the afternoon Rembrandt was sitting on the top of the hill quite near the house watching the traffic in the streets of the town. When he saw his teacher coming towards his father's house, his heart sank because he was sure the teacher had come to tell the parents about his misbehaviour at school. His father called him and the young Rembrandt saw his teacher holding one of the wooden shoes in his hand. He lost his presence of mind and courage as all eyes were turned on him as he came near. He was sure that his father would express his anger to the young Rembrandt and punish him. To his great surprise, his mother spoke to him kindly, saying "Do you really want to be a painter, my child?" The boy couldn't even believe his ears, his heart was full of happiness, and it began to beat more frequently. He was in seventh heaven. Rembrandt's teacher told his parents that he enjoyed his excellent drawings and wanted him to study painting with the famous artist of the town. Both his parents were happy to hear it. Soon he was sent to learn painting. Later Rembrandt painted many wonderful pictures and became famous not only in his country but in the whole world. But in the end he died a poor man.
