Question

Длина прямоугольника c см а ширина в 3раза больше найди периметр прямоугольника?

Answer 1

Длина - с см
ширина - 3с
P=3c+c+3c+c=8c

Answer 2

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle, we can use the formula: perimeter = 2 * (length + width).

Given that the width is 3 times the length, we can represent the width as 3a and the length as a.

Calculation

Using the given information, we can calculate the perimeter as follows:

1. Width (b) = 3a 2. Length (a) = a 3. Perimeter (P) = 2 * (a + 3a)

Now, let's calculate the perimeter using the given values.

Perimeter Calculation

Using the given values, we can calculate the perimeter as follows:

P = 2 * (a + 3a)

P = 2 * (4a)

P = 8a

So, the perimeter of the rectangle is 8a.

This calculation is based on the provided information and the formula for the perimeter of a rectangle.
