8а:

Чтобы найти значения длины и ширины прямоугольника с периметром 8 мм, нужно решить систему уравнений. Периметр (P) прямоугольника равен удвоенной сумме его длины (L) и ширины (W):

P = 2L + 2W

В данном случае P = 8 мм. Таким образом, у нас есть следующая система уравнений:

1. 8 мм = 2L + 2W

2. 420 мм = L

3. 64 см = W (для удобства переведем в миллиметры, так как 1 см = 10 мм)

Тепер мы можем использовать эти уравнения, чтобы найти значения длины (L) и ширины (W):

1. 8 мм = 2L + 2W

2. 420 мм = L

3. 640 мм = W (после перевода см в мм)

Теперь у нас есть значения длины (L = 420 мм) и ширины (W = 640 мм) прямоугольника, удовлетворяющие заданному периметру.

8б:

Для того чтобы найти площадь прямоугольника, нужно умножить его длину на ширину. В данном случае, у вас есть одна из сторон (460 мм), но чтобы найти другую сторону (ширину), вам потребуется дополнительная информация. Если у вас есть только одна измеренная сторона (длина или ширина), то без информации о другой стороне невозможно точно найти площадь прямоугольника.

Для нахождения площади прямоугольника необходимы обе стороны. Если у вас есть информация о второй стороне, предоставьте ее, и я помогу вам вычислить площадь.
