Answer 1

1) переводим дм в см= 30 см
2) (17+30)*2=94 см 
ответ: периметр=94 см

Answer 2

(17+30)*2=94см
94см=9дм 4см

Answer 3

Perimeter of a Rectangle

To find the perimeter of a rectangle, you need to add up the lengths of all its sides. The formula for the perimeter of a rectangle is:

Perimeter = 2 * (Length + Width)

In this case, we have a rectangle with sides measuring 17 cm and 3 dm. To calculate the perimeter, we need to convert the measurements to the same unit. Since 1 dm is equal to 10 cm, we can convert 3 dm to cm by multiplying it by 10.

Converting 3 dm to cm: 3 dm * 10 cm/dm = 30 cm

Now we have the measurements in the same unit:

Length = 17 cm Width = 30 cm

Using the formula for the perimeter of a rectangle, we can calculate:

Perimeter = 2 * (17 cm + 30 cm) = 2 * 47 cm = 94 cm

Therefore, the perimeter of the rectangle with sides measuring 17 cm and 3 dm is 94 cm.
