Question

Если длина прямоугольника 6см,а ширина на 3смдлинее,то периметер прямоугольника равен 18см?

Answer 1

Длинна- 6 см
Ширина-? на 3 см длиннее Д
1)6+3=9 (см)- ширина прямоугольника
P= 9+9+6+6=30 (см)

Answer 2

Ширина получается равна 9
Р=а+в+а+в
Р=9+9+6+6=30
вроде так

Answer 3

Calculation of the Perimeter of a Rectangle

To calculate the perimeter of a rectangle, you need to know the length and width of the rectangle. In this case, the length of the rectangle is given as 6 cm, and the width is 3 cm longer than the length.

Let's calculate the perimeter using the given information.

The formula for the perimeter of a rectangle is:

Perimeter = 2 * (Length + Width)

Substituting the given values:

Length = 6 cm Width = Length + 3 cm = 6 cm + 3 cm = 9 cm

Plugging in the values into the formula:

Perimeter = 2 * (6 cm + 9 cm) = 2 * 15 cm = 30 cm

Therefore, the perimeter of the rectangle is 30 cm.

Answer

If the length of the rectangle is 6 cm and the width is 3 cm longer than the length, then the perimeter of the rectangle is 30 cm.
