Автор ответа: abliznec98

Объяснение:

$s = \frac{a \times b}{2} \times h \\ s = \frac{9 \times 13}{2} \times 10 = 58.5 {m}^{2}$

ninja6791: (9*13*10)/2=585 а где деление на 10 чтобы получить 58,5; и еще m*m*m=m^3

ninja6791: ((a+b)/2)*10 тогда так

Автор ответа: ninja6791

Ответ:110 $m^{2}$

Объяснение:

c+d=b-a=13-9=4 м

S=((c+d)*10)/2+a*h=(4*10)/2+9*10=110 $m^{2}$

1. More than 80 percent of New Zealand’s population are Britons or Europeans.
That's why the New Zealand school system is similar to the British one. Education
is free and compulsory for children between the ages of 6 and 16.The school year
starts in January (after the summer holidays) and ends in December. In most
schools wearing a school uniform is obligatory. For New Zealand teenagers daily
life takes place in school where they stay up to the late afternoon.

2. Canada occupies most of the northern North America continent as well as some
islands. It stretches from the Atlantic Ocean in the east to the Pacific Ocean in the
west. It's also washed by the Arctic Ocean in the north. The country was
discovered in 1497 by John Cabot, an Italian sea captain. About 2% of the
Canadian territory is covered with ice. The eastern part of the country is mainly
valleys and plains. The western territories are made up of the Cordilleras.

3. Most Americans simply call the Independence Day the “Fourth of July”. It
always falls on this day, and it celebrates the signing of the Declaration of
Independence on July 4, 1776. At that time, the people of the 13 British colonies
were involved in a war which had begun in 1775. The colonists were fighting for
freedom from the English. The Declaration of Independence stated it clearly. For
the first time in history the colonies were defined as the United States of America.

4. With great weather, great events and terrific crowds Australia Day in Melbourne
in 2010 was one of the best ever! It is a day for all Australians to get together and,
in whatever way they choose, celebrate being Australian. 1788 is when the British
Fleet first arrived at Sydney Cove and lifted the British flag. Now, major cities
throughout the country celebrate the national day with parades, free food, and
different events.

5. Cambridge lies in East Anglia, about 50 miles north of London. The river Cam
flows through it. It gets the name Cambridge from the river. It's a compact green
city. There is always something to do and to see in the city: walk in the parks and
gardens, visit museums and galleries, enjoy the festivals or relax in small cafés.
The city is best known as the home of Cambridge University, one of the world's
best universities. It was founded in 1209 and it consists of 30 colleges.
