Question

Как найти периметр длины сторон которого 8 дециметров 6 дециметров

Answer 1

Периметр обозначается буквой Р.

а - одна из сторон прямоугольника

b- вторая сторона прямоугольника.

Формула: P=(a+b)*2

РЕШЕНИЕ.

Pпрямоугольника= (8+6)*2= 28(дм.).

ОТВЕТ: 28 дм.

Answer 2

P=2*(8+6)=28 дм
Ответ: периметр равен. 28 дм

Answer 3

Finding the Perimeter of a Shape with Side Lengths of 8 Decimeters and 6 Decimeters

To find the perimeter of a shape with side lengths of 8 decimeters and 6 decimeters, you can use the formula for the perimeter of a polygon, which is the sum of the lengths of all its sides.

Using the Formula P = a + b + c + d

The perimeter (P) of a shape with side lengths a, b, c, and d is given by the formula P = a + b + c + d, where a, b, c, and d are the lengths of the sides.

Using the Formula P = 2 * (a + b) for a Quadrilateral

For a quadrilateral, the perimeter can also be calculated using the formula P = 2 * (a + b), where a and b are the lengths of two adjacent sides.

Calculating the Perimeter

Using the given side lengths of 8 decimeters and 6 decimeters, we can calculate the perimeter as follows:

P = 2 * (8 + 6) = 2 * 14 = 28

So, the perimeter of the shape with side lengths of 8 decimeters and 6 decimeters is 28 decimeters.

Calculating the Area of the Shape

To calculate the area of the shape, we can use the formula for the area of a rectangle, which is the product of its length and width.

Using the Formula S = a * b for a Rectangle

The area (S) of a rectangle with side lengths a and b is given by the formula S = a * b, where a and b are the lengths of the sides.

Calculating the Area

Using the given side lengths of 8 decimeters and 6 decimeters, we can calculate the area as follows:

S = 8 * 6 = 48

So, the area of the shape with side lengths of 8 decimeters and 6 decimeters is 48 square decimeters.

In summary, the perimeter of the shape is 28 decimeters and the area is 48 square decimeters.
