Ширина Х м ; длина ( 7/5 ) Х м( 7/5 ) Х - Х = 13( 2/5 ) Х = 13 Х = 65/2 Х = 32,5 ( м ) ширина ( 7/5 ) * ( 65/2 ) = 455/10 = 45,5 ( м ) длина S = 32,5 * 45,5 = 1478,75 ( кв м ) площадь

Помогите перевести текст! Заранее благодарен.

In my opinion materialism is not a bad point of our society. 1 try not to be too materialistic, but I think everyone is a little bit. We live in a competitive world where success is important, so people become more materialistic. I think the way you look is really important especially for teenagers who want to be a part of a group. So it's natural that people think of money and possessions.
On the other hand, materialistic people think that money is everything in the world and being rich is the only way of being successful. It's important for them to have designer labels and fashionable things. Some people can even kill others to have more money or possessions. In this case we can say that money is the root of the evil. However, there are very important things in our life that can't be bought, such as love and friendship.
Of course, you know that there are a lot of people who have little money. Lack of money can cause real problems, such as bad health, stress or even crime. But many people are poor. They never waste money and they spend it on the essentials. More than that, they learn to find unusual in usual things, and this makes their life interesting. I don't think that money is the only way of being successful in life.
But it cannot be denied that money is an essential part of our life. There are a lot of rich people, but not all of them are materialistic, for example, Bill Gates. You wouldn't look twice at him if he passed you in the street because he looks like an ordinary person. He likes fast food and casual clothes. He is always on the company campus. But Bill Gates is not snobbish or ambitious. More than that, he is a noted philanthropist who donated a lot of money to non-profit educational organizations. Yet he is one of the most successful men in the world.
To get success in life you should be creative, intelligent, hard working. You'll never get success if you wait for someone to bring it to you. You have to get up and get it yourself.
The only thing I want to say is that you needn't be rich to be happy. A clever person can always find beauty in ordinary things. And I think that only such things can make you happy.
