Ответы

Автор ответа: Urbanmonk

x - сторона квадрата
p - площадь квадрата

x^2 = p
x = корень_квадратный(p);

Автор ответа: ruhlov1953

а если ещё не проходили эти квадратные корни?

Автор ответа: Urbanmonk

Хм. Если это квадрат, то все стороны равны. То есть площадь - это квадрат какого-то числа.

Автор ответа: Urbanmonk

Если оно небольшое, то посмотреть таблицу квадратов чисел на обратной стороне тетради. )

Автор ответа: Urbanmonk

Без знания кв. корня, думаю, что только рассуждением типа "какое число при умножении само на себя дает такую площадь"
