Question

Найди периметр прямоугольника со сторонами 3дм и 5дм. Запиши в тетрадь.

Answer 1

(3+5)*2=16(дм)-периметр прямоугольника.
Или
3+5=8(дм)-ширина и длина.
8*2=16(дм)-периметр прямоугольника.

Answer 2

Perimeter of a Rectangle

To find the perimeter of a rectangle, you need to add up the lengths of all its sides. In this case, we have a rectangle with sides measuring 3 dm and 5 dm.

The formula for the perimeter of a rectangle is:

Perimeter = 2 * (length + width)

Let's substitute the values into the formula:

Perimeter = 2 * (3 dm + 5 dm)

Calculating the perimeter:

Perimeter = 2 * (8 dm)

Perimeter = 16 dm

Therefore, the perimeter of the rectangle with sides measuring 3 dm and 5 dm is 16 dm.

Please note that the unit of measurement used here is decimeters (dm).
