Question

От прямоугольника со сторонами 6 см и 8 см с помощью одного разреза отрезали полосу 6 см на 2 см. Чему равна площадь оставшейся части? Дайте ответ в квадратных сантиметрах.

Answer 1

Найдем вначале площадь всей фигуры до разреза: 6*8=42 см^2
Найдем площадь отрезанной фигуры: 2*6=12 см^2
Найдем площадь оставшейся части: 42-12= 30 см^2
Ответ: 30 см^2

Answer 2

Calculation of the Remaining Area

To find the area of the remaining part after cutting a strip of size 6 cm by 2 cm from a rectangle with sides measuring 6 cm and 8 cm, we can subtract the area of the cut strip from the total area of the rectangle.

The total area of the rectangle is given by the formula: Area = length × width.

In this case, the length of the rectangle is 8 cm and the width is 6 cm.

Therefore, the total area of the rectangle is: Area = 8 cm × 6 cm = 48 cm².

Next, we need to calculate the area of the cut strip. The dimensions of the strip are given as 6 cm by 2 cm.

Therefore, the area of the cut strip is: Area of strip = 6 cm × 2 cm = 12 cm².

To find the area of the remaining part, we subtract the area of the cut strip from the total area of the rectangle:

Remaining area = Total area - Area of strip = 48 cm² - 12 cm² = 36 cm².

Therefore, the area of the remaining part is 36 cm².
