До прямоугольника 36 сантиметра что в 4 раза больше его ширины Найди периметр прямоугольника

Answer 1

36:4=9
Р=(36+9)х2=70см

Answer 2

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle, we can use the formula: P = 2 * (a + b), where a and b are the length and width of the rectangle, respectively.

Given that the length of the rectangle is 36 centimeters and its width is 4 times smaller, we can calculate the width and then find the perimeter.

Calculating the Width of the Rectangle

To find the width of the rectangle, we can use the information that the width is 4 times smaller than the length.

The width (b) can be calculated using the formula: b = a / 4, where a is the length of the rectangle.

Using this formula, we can calculate the width of the rectangle: - a = 36 - b = 36 / 4 = 9

Calculating the Perimeter

Now that we have the length and width of the rectangle, we can calculate the perimeter using the formula: P = 2 * (a + b).

Substituting the values: - a = 36 - b = 9

We get: - P = 2 * (36 + 9) - P = 2 * 45 - P = 90

Therefore, the perimeter of the rectangle is 90 centimeters.
