Так как это квадратная плитка, то длина и ширина равны 11. Площадь квадрата - длина*ширина(11*11), будет 121. 121-44 съеденных кусочка = 77.

ответ: 77 квадратиков осталось

This is my first year at university and I (not/get used to) a new style of life yet. I know that it's going to be easier in several months when I (learn) how to deal with tasks and activities which format is unfamiliar to me and how to plan the day to ensure that everything (write) and submitted on time. The right strategy is very important. I wish someone could help me to choose the best one. In my turn I could share my personal experience with those who are still at scholl. I (learn) at school for 11 years, which gives me a reason to consider myself an expert on most school matters. And as an expert, I think that it is very important to work out your own strategy on how to deal with school assignments. Everyone (want) to spend as little time as possible on homework and yet to get the maximum result. Unfortunately, not everyone manages to. When I was at junior school, I (start) my homework with the subjectsI liked most of all. Naturally, they were the easiest and most enjoyable subjects like drawing and reading. More challenging maths and grammar (put off) till later. When Mum came from work, she found that the most important, in her opinion, tasks (not/do) yet and we used to spend evenings over my notebooks. She (keep) telling me that the priorities had to (change) but I ignored her words. Unfortunately, my strategy (not/change) at senior school. Not long before the exams I realised that the difficult subjects like physics and geometry (neglect) by me for years. Desperate measures (need) to improve the situation and to avoid the exam fail. Fortunately, I passed the exam, but it (teach) me a lesson for the rest of my life.
