Пошаговое объяснение:

1 +2 сторона = 192

2+3 сторона = 109

Р= 225

192+109-х=225

192+109-225=х

х= 76 см вторая сторона

192-76= 116 см первая сторона

109-76=33см третья сторона

проверка:

116+32+76= 225 см

William Shakespeare, the greatest and most famous of English writers, and probably the greatest playwright who has ever lived, was born on the 23d of April, 1564, in Stratford-on-Avon.
In spite of his fame we know very little about his life. At the age of six he was sent to school, but had to leave it at the age of 13. His father, John Shakespeare, was a glove-maker, and when he fell into debt, William had to help him in the trade.
Just what William did between his fourteenth and eighteenth year isn't known. At the age of eighteen, he married Anne Hathaway. Ann was eight years older than her husband and the marriage wasn't a happy one.
When Shakespeare was twenty-one, he went to London. We don't know why he left Stratford-on-Avon. There is a story that Shakespeare's first job in London was holding rich men's horses at the theatre door. But nobody can be sure that this story is true.
Later, Shakespeare became an actor and a member of a very successful acting company. It's highly probable that The Comedy of Errors, Romeo and Juliet and some other plays by Shakespeare were performed for the first time on this stage.
Very soon, however, the actors were told that they could no longer use the land that their theatre was built on and the company had nowhere else to perform. There is a story that in the dead of night the whole acting troop took down their theatre, timber by timber, brick by brick. They carried it across the river and rebuilt it. The new theatre was called the Globe.
Shakespeare wrote 37 plays: 10 tragedies (such as Hamlet, King Lear, Othello, Macbeth), 17 comedies (such as As You Like It, Twelfth Night, Much Ado About Nothing), 10 historical plays (such as Henry IV, Richard III.). He also left 7 books of poems. His 154 sonnets are known all over the world nowadays.
Most of Shakespeare's plays were not published in his lifetime. So some of them may have been lost in the fire when the Globe burnt down in 1613.
Shakespeare spent the last years of his life at Stratford, where he died, ironically, on the same date as his birthday, the 23d of April, 1616. He was buried in the church of Stratford. A monument was erected to the memory of the great playwright in the Poet's Corner in Westminster Abbey. In 1997, Shakespeare's Globe was restored.
