Question

Начерти два прямоугольника. Длина первого 7 см, ширина 3 см. Длина второго 3 см, ширина 2 см. Во сколько раз периметр первого прямоугольника больше периметра второго? Плиз помогите 10 баллов даю 3 класс

Answer 1

Периметр первого=(7+3)*2=20 см
периметр второго=(3+2)*2=10см
20:10=2 
ответ:в 2 раза

Answer 2

Drawing Rectangles

Let's start by drawing two rectangles based on the given dimensions:

- Rectangle 1: - Length: 7 cm - Width: 3 cm

- Rectangle 2: - Length: 3 cm - Width: 2 cm

Calculating Perimeters

To find the perimeters of the rectangles, we can use the formula: Perimeter = 2 * (Length + Width)

For Rectangle 1: - Perimeter = 2 * (7 + 3) = 2 * 10 = 20 cm

For Rectangle 2: - Perimeter = 2 * (3 + 2) = 2 * 5 = 10 cm

Finding the Ratio

Now, let's calculate how many times the perimeter of Rectangle 1 is greater than the perimeter of Rectangle 2: - 20 cm (Perimeter of Rectangle 1) / 10 cm (Perimeter of Rectangle 2) = 2

So, the perimeter of Rectangle 1 is 2 times greater than the perimeter of Rectangle 2.
