Ответ: В) - 60

Поскольку, если периметр квадрата 8+8+8+8, значит у прямоугольника две стороны должны быть больше(длины), чем другие две стороны(ширины). Значит в 2ух сторонах добавим 2(8+2=10), а в 2ух убавим 2(8-2=6) Площадь равна умножение длины на ширину следовательно 10*6=60

Итак, задание на урок:
1. Прочитать текст и расставить абзацы в правильном порядке.

1. After two hours, we heard a noise. It was Juan and he was angry. 'You're very lucky,' he said. But we were very happy. ‘We're never going to follow monkeys again,' we promised. Juan laughed, 'Come on. Let's go back to camp.'
2. We wanted to take photos of monkeys. We got up early and walked into the jungle. We didn't have to go far before we heard some monkeys. We were excited and we followed the monkeys for about ten minutes. Suddenly, Peter stopped. He was worried. 'I'm not going to walk further,' he said. ‘We'll get lost. I'm going back.'
3. My brother Peter and I were on a jungle wildlife holiday with six other people and Juan our guide. It was an amazing experience and we saw lots of monkeys, crocodiles and huge snakes. But one morning Peter and I did a very stupid thing.
4. We looked around us. There were trees everywhere. The campsite wasn't far, but we had no idea which direction to take. I think we are already lost,' Peter said. 'How are we going to get back? Nobody knows where we are. They'll never find us.'
5. Then it started to rain. Luckily, I had a waterproof coat. We sat on our rucksacks with the coat over our heads. There were loads of mosquitoes and we had no insect repellent. We were scared and miserable.
