Пусть А(-1;10); В(1;10), С (16;2), D(-7;2)

АВ=√((-1-1)²+(10-10)²)=2

ВС =√((16-1)²+(2-10)²)=√(225+64)=17

СD=√((23)²+0²)=23

АD=√((-7+1)²+(2-10)²)=10

Р=АВ+ВС+СD+АD= 2+17+23+10=52

annalicapina: Спасибо большое за старание!

2.)Read the text. Then say whether the statements are true (T) or false (F). Hopes for a better environment Angela, 18 About me: I study international relations. I like reading. Fears: When I was at school, a guy laughed when I was talking to a friend about climate change. He said ‘Even if you care, the Earth is going to end anyway.’ I was so annoyed.
