Like everyone, I have my private hobbies. I have many hobbies such as watching horror films, reading novels, listening to music e.t.c But I like traveling best. Firstly, when I have to study or work too much, I usually feel tired and bored,so I want to refesh myself and travelling is a good way for me to relax.Secondly, travelling helps me widen my knowledge because I can pick up a lot of different cultures and study so much from them.Besides,I can learn foreign languages when I travel abroad. On the other hand, travelling makes my life more interesting because I can meet lots of people all over the world and make new friends.Finally, I can admire true beauty and enjoy it when I go to different places. However, it's hard for me to travel abroad because I'm always busy studying and I don't have much money.To sum up, I love travelling very much because it not only cheer me up but also keep my eyes open

(Bài nay minh khong cop mang 100%)

My hobby is collecting stams, when I was still a

baby, my mother began to collect for me, of course she didn't let me touch the stamps till I was old enough not to spoil them. I remember that it was on my 2nd birthday, that the first put then in to my hands, they were in four thick books, but since that twice I've added 3 more,so that now I've a bigger collection than any of my friends. How do I get my stamps? I've friends both and other lands who send me stamps. Now I'm working for my living so I don't have as much time as before to send on my stamps, but in the evening what can be better than to sit down at a table with my books arranging new stamps in them writing in the name of me.

ta có: \(S_{\Delta ANM}=\frac{AN\times AM}{2}=4cm^2\)

\(\Rightarrow AN\times AM=8\)

\(\Rightarrow\left(3\times AN\right)\times\left(2\times AM\right)=8\times3\times2\)

mà \(AN=\frac{1}{3}\times AB\Rightarrow AB=3\times AN\)

\(AM=\frac{1}{2}\times AC\Rightarrow AC=2\times AM\)

\(\Rightarrow AB\times AC=48\)

\(\Rightarrow S_{\Delta ABC}=\frac{AB\times AC}{2}\)

thay số: \(S_{\Delta ABC}=\frac{48}{2}\)

\(S_{\Delta ABC}=24cm^2\)
