Question

Размеры платка,имеющего форму прямаугольника ,равны 60см и 30см Уменьше размеры прямоугольника в 10 раз Вычесли периметр и площадь первого и второго прямоугоников

Answer 1

Второй прямоугольник равен 18см кв., а периметр тоже 18см. У платка площадь 1800см кв., а периметр 180см.

Answer 2

Calculation of Perimeter and Area of Rectangles

To calculate the perimeter and area of the given rectangles, we need to follow these steps:

1. Determine the dimensions of the first rectangle: - Length: 60 cm - Width: 30 cm

2. Determine the dimensions of the second rectangle, which is 10 times smaller than the first rectangle: - Length: 60 cm / 10 = 6 cm - Width: 30 cm / 10 = 3 cm

3. Calculate the perimeter of the first rectangle: - Perimeter = 2 * (Length + Width) - Perimeter = 2 * (60 cm + 30 cm) - Perimeter = 2 * 90 cm - Perimeter = 180 cm

4. Calculate the perimeter of the second rectangle: - Perimeter = 2 * (Length + Width) - Perimeter = 2 * (6 cm + 3 cm) - Perimeter = 2 * 9 cm - Perimeter = 18 cm

5. Calculate the area of the first rectangle: - Area = Length * Width - Area = 60 cm * 30 cm - Area = 1800 cm²

6. Calculate the area of the second rectangle: - Area = Length * Width - Area = 6 cm * 3 cm - Area = 18 cm²

Therefore, the perimeter and area of the first rectangle are: - Perimeter: 180 cm - Area: 1800 cm²

And the perimeter and area of the second rectangle are: - Perimeter: 18 cm - Area: 18 cm²
