Question

Начертить квадрат с длиной стороны 3см 5мм.Вычислить его периметр и записать результат в дециметрах и сантиметрах?

Answer 1

3см 5 мм=35 мм
Р кв=4*а

35*4=140 мм=14 см =1 дм 4 см

Answer 2

Drawing a Square

To draw a square with a side length of 3 cm 5 mm, we can use the following steps:

1. Start with a straight line segment of 3 cm. 2. From one end of the line segment, draw another line segment perpendicular to the first one, also measuring 3 cm. 3. Connect the open ends of the two line segments with two more line segments, each measuring 3 cm. 4. Finally, connect the remaining open ends of the line segments to complete the square.

The resulting square will have a side length of 3 cm 5 mm.

Calculating the Perimeter

To calculate the perimeter of the square, we need to add up the lengths of all four sides. Since all sides of a square are equal, we can multiply the length of one side by 4 to find the perimeter.

Given that the side length is 3 cm 5 mm, we can convert it to centimeters by adding the length in centimeters (3 cm) to the length in millimeters (5 mm) converted to centimeters.

Converting 5 mm to centimeters: 5 mm = 0.5 cm

So, the side length in centimeters is 3 cm + 0.5 cm = 3.5 cm.

Now, we can calculate the perimeter:

Perimeter = 4 * side length

Perimeter = 4 * 3.5 cm

Perimeter = 14 cm

Therefore, the perimeter of the square is 14 centimeters.

To express the result in decimeters and centimeters, we can convert 14 centimeters to decimeters and centimeters:

14 centimeters = 1 decimeter + 4 centimeters

So, the perimeter of the square is 1 decimeter and 4 centimeters.

Conclusion

In conclusion, a square with a side length of 3 cm 5 mm has a perimeter of 14 centimeters, which is equivalent to 1 decimeter and 4 centimeters.
