Question

Длина прямоугольника 6м а ширина 3дм чему равен периметр прямоугольника

Answer 1

Периметр- сумма  всех сторон. у нас прямоугольни, значит, нудно к двум длинам прибавить две ширины. Только они должны быть в одних единицах. Длина 6м=60дм. Периметр: 2х60+2х3=126(дм). Или 12,6м. Или 12м 6дм. 

Answer 2

P = длинна Х ширина
3дм = 30см = 0,3м
6м Х 0.3м = 20см

Answer 3

Calculation of the Perimeter of a Rectangle

To calculate the perimeter of a rectangle, you need to know the length and width of the rectangle. In this case, the length of the rectangle is given as 6 meters, and the width is given as 3 decimeters (dm).

To find the perimeter, you can use the formula: Perimeter = 2 * (Length + Width).

Substituting the given values into the formula, we have:

Perimeter = 2 * (6m + 3dm)

To perform the calculation, we need to convert the width from decimeters to meters. Since 1 meter is equal to 10 decimeters, the width of 3 decimeters is equal to 0.3 meters.

Perimeter = 2 * (6m + 0.3m)

Simplifying the expression, we get:

Perimeter = 2 * 6.3m

Calculating the value, we find:

Perimeter = 12.6m

Therefore, the perimeter of the rectangle is 12.6 meters.
