y=x+3 - прямая, пересекает прямую y = 0 в точке A(-3;0), прямую x = -1 - в точке B(-1;2).
Прямые y = 0 и x = -1 пересекаются в точке C(-1;0).
Получаем треугольник ABC, он прямоугольный с катетами AC = 2 и BC = 2.
По формуле для площади прямоугольного треугольника:
S = (1/2) *a*b (a,b - длины катетов)
S = 2*2/2 = 2.

It’s a well-known fact that the climate of the UK is influenced by the sea, which is nowhere farther than 120 km.The sea warms slowly in summer and brings cool breezes overland, and it cools slowly in winter, generously sharing its warmth with land areas.The UK’s climate is mild: it is never too hot
or never too cold.One would expect similar weather in all seasons without much contrast between them.

2. But my first-hand experience will help me draw a different picture – a clear picture of four seasons.It is strongly influenced by the climate of my hot, sunny Australia.Here we often have to deal with droughts and wildfires caused by lack
of rain for days, months and even years!The UK never experiences a rain deficit, even during the summer months, which
are warm, and even hot in July! Heatwaves can be an exception
though.

3. On official meteorological sites, you can read that precipitation is spread evenly throughout the year with annual aver-
ages of 885 mm and 133 days of rain or snow.If you have lived
in the mild “maritime” climate of the UK, you might have
a feeling that precipitation falls 24/7 in the form of drizzle,
short showers, light or heavy rain – sometimes, real down-
pours!Britain seldom suffers from lack of rain, so green grass
covers the gentle hills and valleys, plains and garden lawns almost all the year round.Well-fed by rain, all plants look so full of life and so different from the vegetation in arid and semiarid climates of most of Australia.

4. Winter might signal its arrival with a little snow, especially in the north – in Yorkshire in England and in the mountainous areas of Scotland.It occurs
after short, mostly dull autumn days,
cheered up by the bright colours
of autumn leaves, which look even
brighter under the blue sky of an Indian summer.Winter may start in
late November with below freezing
temperatures at night, and as a result, icy roads and paths, causing injuries and longer journeys because of the slippery surfaces.

5. If there is a possibility of dangerous impacts, caused by
extreme weather, the Met Office issues warnings for rain, fog,
snow, ice and wind.Flood warnings are issued by Environment
Agencies.There is no definite season for floods – they can occur any time in any season.They are a big problem and the
flood damage costs huge amounts of money.

6. In spite of the problems caused by weather or weather extremes, British people know how to weather the storm and how to avoid feeling under the weather. They know how to make the most
of each season. Think of Christmas, for example, its beauty, shining with millions of sparkling
lights on houses, in shop windows, on Christmas Trees in every home
and in the streets! The British are optimistic – time flies! Spring will soon begin in March, bringing
the long Easter holiday. And the possibility to escape to warmer
climates in summer is just round the corner!

7. Here’s one more interesting observation about UK’s
weather. It can be described as unpredictable – because it is very changeable. Any weather is possible during the day. No wonder, the British like to talk
about the weather – they praise it or blame it for destroyed plans, cancelled journeys and activities. Actually, they know how to deal
with the naughty weather – a ‘brolly’
rainproof wear and layers of clothes.
As they say, “Rain or shine, keep calm
and carry on.”
