Пошаговое объяснение:

Пусть ширина прямоугольника равна х м, а длина больше на 9 м, т.е. (х+9) м.

Сумма всех сторон х + (х+9) + х + (х + 9) равна периметру 62.

Составляем уравнение

х + (х + 9) + х + (х + 9) = 62

4х + 18 = 62

4х = 62 - 18

4х = 44

х = 11

(х + 9 ) = 11 + 9 = 20

S = 11·20 = 220 кв. м

Ответ: S = 220 кв. м

ОТВЕТИТЬ НА ВОПРОСЫ ПО ТЕКСТУ The Galapagos Islands in the Pacific Ocean are one of the natural wonders of the world. One thousand kilometres from South American coast, the Galapagos are home for many rare animals, such as giant tortoises, sea birds and dolphins.
The islands first became famous in 1859 when Charles Darwin wrote about them in his book, The Origin of Species. When Charles Darwin visited the islands, he found there a key to “that mystery of mysteries- the first appearance of new life on this earth”.
Today the islands belong to Ecuador, and 97 % of the area is a national park. However, despite this protection, the park is in danger. The most serious threat comes from illegal fishing, which is slowly destroying marine life. Every day illegal nets trap and kill sharks, pelicans and dolphins.
Another treat comes from animals brought over by people who have come to live on the islands. Dogs and cats eat the sea birds, and rats and pigs eat turtle eggs. Getting these animals off the island is difficult and expensive.
Although tourism is seen as a positive thing, it too has caused problems. The population of Galapagos is growing fast, with people from the mainland looking for a job. Unfortunately, the islands’ resources can’t support this growth.
Today the Galapagos is still a wonderful place, but how long will this last? “It’s impossible to protect the park on our own”, says park ranger Diego Correa. “We need help and resources from outside, and it’s up to everyone to make a contribution- the Galapagos belong to the whole world”.

1. What type of animals live in the Galapagos?
2. How did the island become well known?
3. Who owns the islands today?
4. What problems with population do the islands have?
5. What threats do destroy marine life?
6. Do the owners of the park manage to support it on their own?
