72х30 = 2160 (кв. метров) - площадь огорода
2160- (2160х3/4) = 2160-1620 = 540 ( кв метром) - 1/4 часть огорода
540: 2 = 270 (кв метром)- занято морковью

Текст :
Beyond Our Dreams!
From my point of view our college is modern and
well-designed. It is a three -storey building with a
sports ground behind it. I really think it is the best
educational institution in Moscow. We even have an
inside Swimming p0!
On the ground floor there are the classrooms for the first-year students, workshops
and a library There are all kinds of tools and machines in the workshops. In the
library two librarians help students to find the books they need. In the reading
room there are laptops which we can use during
the breaks and after classes.
Our canteen is spacious, light and clean. We have
our meals there.
The physical training lessons take place in the
gymnasium and the swimming pool. We like to
go there even after the lessons. To the left of the
gym there is a hall and a staircase. The staircase
leads to the first floor.
The classrooms are well-equipped. Each room
has a teacher's table, students desks, a board,
a computer and a multimedia projection unit. There are special classrooms for
Chemistry, Physics, Biology, History, Geography, English and Russian. My English
classroom is on the second floor It has three big windows. There are lots of potted
plants on the window sills, and we take good care of them. The board in our
classroom is magnetic. We write with markers on it and attach our projects to it with
magnets. Next to the board there are maps of Russia
and Great Britain, various grammar tables and charts.
There is a computer in the right-hand corner We often
listen to original English texts, songs and watch films
on a big screen which make our lessons interesting
I like my college. It provides us with everything
to help us become good specialists.
