Question

Задание номер 2 в кружочке. ВЫЧИСЛИ ПЕРИМЕТР ПРЯМОУГОЛЬНИКА. В ВЫСОТУ 4 дм 7 см в ширину 6 дм 5 см

Answer 1

(47+65)*2=112*2=224см=22дм 4см
Ответ: периметр прямоугольника 22дм 4 см

Answer 2

Calculating the Perimeter of a Rectangle

To calculate the perimeter of a rectangle, we can use the formula:

Perimeter = 2 * (length + width)

Given: - Length = 4 dm 7 cm - Width = 6 dm 5 cm

Conversion of Measurements to a Common Unit

First, let's convert all measurements to the same unit, either decimeters (dm) or centimeters (cm).

- Length = 4 dm 7 cm = 47 cm - Width = 6 dm 5 cm = 65 cm

Calculating the Perimeter

Now, we can use the formula to calculate the perimeter:

Perimeter = 2 * (47 cm + 65 cm) Perimeter = 2 * 112 cm Perimeter = 224 cm

So, the perimeter of the rectangle is 224 cm.
