Відповідь:12 см,15 см,24 см

Покрокове пояснення:Нехай х-коефіцієнт пропорційності,тоді сторони дорівнюватимуть 4х,5х,8х

Так як периметр 51 складаємо рівняння

4х+5х+8х=51

17х=51

х=3

Тоді з цього сторони вийдуть:4*3=12

5*3=15

8*3=24

1. What nature-friendly ideas started a new branch in the tourism business? A
2. What means of transport is the most popular with tourists?
3. Why can tourism be dangerous to nature?
4. What are the reasons that make people go on a trip?
5. What kind of tourism is getting popular with elderly people?
6. Why does travelling make people smarter?
7. What are the ways to save money while travelling?

A. Tourism has become a popular activity. Indeed, nowadays people travel more, and further, than they used to. The main reasons for tourism are: recreation, leisure and business. When travelling for recreation, people want to escape their stressful daily routine and to relax. Beach holidays are an example of such tourism. Business trips involve going to a distant place in order to settle business issues.
B. Whether on a business trip or on a honeymoon, people want to explore the place they are in. They go on excursions, try new activities like diving or mountain climbing and learn about the historical background of the place and its cultural peculiarities. Sometimes they find out amazing facts about people and places and about themselves too! In fact, when people travel, they broaden their horizons.
C. A new branch of tourism is ecotourism. It involves visiting relatively untouched places in remote areas. Ecotourism is often misinterpreted as any form of tourism involving wildlife - but it’s completely different from jungle tourism or safari. Eco-tourists are against disturbing the environment; even taking photos is not recommended. Take only memories and leave only footprints is a very popular slogan for them.
D. By educational tourism, most people mean different versions of Learn and Travel Programmes for students. But it’s not only for the young and brave. Lots of training and educational programmes for adults are offered in different corners of the world. Retired people participate in these programmes too. They gladly enroll on overseas courses ranging from gardening and design to computer skills and programming.
E. If possible, consider means of transport other than the plane. Rapidly increasing numbers of flights have put the environment in danger. Planes pollute the air, which results in global warming. In fact, tourism is not harmless fun as many may think: new airports and tourist infrastructure, pollution and crowds of noisy tourists make wild animals migrate, which may decrease their population or even make them extinct.
F.
With all its benefits, travelling is still a very expensive activity and may not fit every budget. To reduce the costs, avoid travelling in high season when flight tickets and hotels are overpriced. Remember that, along with expensive destinations, there are less prestigious but even more interesting places. When planning a trip, find out about low-cost airlines, discounts and special offers.
