Question

Помогите пожалуйста: найдите периметр прямоугольника со сторонами: 4,52 м и 3,7 дм. И решите уровнение ф) 46,73*х+53,278х=268,05 Б) 38,72*х-12,888*х=52,3-24,038 Помогите пожалуйста!))

Answer 1

(4,52*2+3,7*2)=16,44


46,73*x+53,278x=268,05
100,007x=268
x=100,008:268
x=0,37316418



38,72*x-12,888*x=52,3-24,038
51,608x=28,262
x=28,262:51,608
x=0,54762827

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 4.52 meters and 3.7 decimeters.

To calculate the perimeter, we need to convert the length of the sides to the same unit. Since 1 meter is equal to 10 decimeters, we can convert the length of the sides as follows:

- Length of the first side: 4.52 meters = 45.2 decimeters - Length of the second side: 3.7 decimeters

Now, we can calculate the perimeter by adding up the lengths of the sides:

Perimeter = Length of the first side + Length of the second side

Perimeter = 45.2 decimeters + 3.7 decimeters

Perimeter = 48.9 decimeters

Therefore, the perimeter of the rectangle is 48.9 decimeters.
