Question

Длина прямоугольника равна 8 см,а ширина-на c см меньше.Запиши в виде выражения его периметр. Помогите пожалуйста!!!

Answer 1

На с см?
Это как понимать?

Answer 2

ширина 8-c

Р=2(а+в)

Р=2(8+8-с)=2(16-с)

Answer 3

Calculating the Perimeter of a Rectangle

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

Perimeter (P) = 2 * (length + width)

Given that the length of the rectangle is 8 cm and the width is c cm less than the length, we can express the width as (8 - c) cm.

So, the expression for the perimeter of the rectangle is:

P = 2 * (8 + (8 - c))

Let's simplify this expression to find the perimeter.

P = 2 * (8 + 8 - c)

P = 2 * (16 - c)

P = 32 - 2c

Therefore, the expression for the perimeter of the rectangle is 32 - 2c.
