0,3а
Объяснение:
Ширина треугольника: 30 см = 0,3м.
Площадь прямоугольника: длина умноженная на ширину (S=a*b).
По условию, длина равна a, а ширина - 0,3м.
Следовательно, S=0,3*a (м²)

Find in the text the sentences containing the Complex Object.
Washington, DC is the capital of the United States of America. It is situated in the mouth of the Potomac River, in the District of Colum bia (DC), not belonging to any state. The city is unique in its own way — it was specially designed as the capital of the USA. The archi tect, who drew up the plan of the city, Pierre 1’Enfant, wanted it to be very convenient. The place for the capital was chosen by the first pres ident, George Washington, and in 1800 the Government moved there.
There are a lot of Governmental offices, but probably the best known, as well as the most important for the country’s life are the White House and the Capitol. The White House is the official residence of the Pres ident of the United States. It was built in 1799. It is a three-storeyedhouse where the President and his family live. At the same time it is the place where official receptions are held and the administration gathers for the meetings. The Capitol is the seat of the Congress. The comer stone of the Congress was laid by George Washington in 1790. The Congress has two chambers: the House of Representatives and the Senate.
The city of Washington, DC is rather large and very beautiful, being at the same time different from all the other cities in the USA, because there are no skyscrapers. According to the law, no house in Washing ton, DC must be higher than the Capitol.
Washington, DC has the population of about 900,000 people. Being the administrative centre of the country, it doesn’t have any industry. They say, nothing is produced in Washington, DC except wastepaper.
Thousands of documents are drafted, approved or denied in the city every day. People living there either belong to the administration, or are employed in the service industry. Besides, thousands of tourists come to see the capital of the country. There is a lot to be seen: Thomas Jefferson Memorial, the Library of Congress, the Washington Monu ment and much more. The Washington Monument is the most remark able of these: it is a column rising 160 metres, and from the top of it the visitors can enjoy the view over the city. Among the attractions of the capital it is necessary to mention the museums: the National Gallery of Art, the National Museum of History and Technology, and others.
