Answer 1

1)8:2=4(см.)- ширина
2) 4+4+8+8= 24(см.)- периметр
Ответ: 24 сантиметра

Answer 2

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle when the length is 8 centimeters and it is twice the width, we can use the formula for the perimeter of a rectangle, which is P = 2 * (a + b), where a and b are the length and width of the rectangle, respectively.

Given that the length is 8 centimeters and it is twice the width, we can calculate the width as follows:

1. Calculating the Width: - Let's assume the width of the rectangle is x. - According to the given information, the length is twice the width, so the length (8 cm) = 2 * width (x). - Solving for x, we get x = 8 / 2 = 4 cm.

Now that we have the length and width, we can calculate the perimeter using the formula P = 2 * (a + b).

2. Calculating the Perimeter: - P = 2 * (8 + 4) - P = 2 * 12 - P = 24 cm

So, the perimeter of the rectangle is 24 centimeters.
