Здравствуйте!

Ответ:

52 м.

Пошаговое объяснение:

Длина- 18 м

Ширина- на 10 м меньше

Периметр-?

Ширина равна:

18 м- 10 м=8 м

Периметр равен удвоенному произведению длины и ширины: P=2(a+b)

Периметр равен:

2×(8м+18м)=2×26м=52 м.

Lisa West went to meet a professional body piercer and asked

WHAT IS THE POINT?

Everywhere you look these days, you can see people that have got rings – hanging from ears and pushed through noses, lips and and eyebrows. And they are in lots of other places that you can’t see, too.

Mick Shannon, who is a qualified body piercer, took me to his salon. I was looking at the walls, covered with photos of clients showing off their rings and jewellery and Mick pointed out his certificate, which was on the wall. “ Some people give our profession a bad name,” he said.

“ They don’t clean their equipment, which shows they don’t know what they’re doing. I’ve known people who have got diseases like hepatitis from cheap ear-piercing guns. I only pierce young people whose parent or guardian is with them. And they have to be over fifteen to have their navel done and over eighteen for their tongue.”

Is it an expensive fashion? “ That depends. Ears, costing $8, are cheap, eyebrows are about $ 35, and the tongue over $ 100. Anything else I have to negotiate!”

I watched Mick pierce a girl’s navel. First he marked the area where he had disinfected the skin, then he pushed a needle through. He finished by giving the girl advice on how to help the skin get better, which was a nice professional touch.

I asked the girl why she had wanted her navel pierced. “ I don’t know. I just like the idea. It’ll be a little secret that I won’t share with anyone!” Did she think it was a way of rebelling? “No,” she laughed, “ but I don’t suppose my mother will like it ... if she ever finds out!”
