Question

Периметр прямоугольника 24 см одна страна этого прямоугольника имеют имеет Длину на 2 см Больше чем другая найди длину каждой стороны этого прямоугольника

Answer 1

1) 24:2=12
2) (12-2):2=5
3) (12+2):2=7

Answer 2

Х-ширина
х+2 -длина
(х+х+2)*2=24
2х+2=24/2
2х=12-2
х=10/2
х=5 - ширина
5+2=7 - длина

Answer 3

Perimeter of a Rectangle

To find the length of each side of a rectangle given that the perimeter is 24 cm and one side is 2 cm longer than the other, we can use the formula for the perimeter of a rectangle:

Perimeter = 2 * (Length + Width)

Let's denote the length of the rectangle as 'a' and the width as 'b'. We are given that one side is 2 cm longer than the other, so we can express the length and width as follows:

a = b + 2

Substituting this into the perimeter formula, we get:

Perimeter = 2 * (b + 2 + b)

Simplifying further:

Perimeter = 2 * (2b + 2)

Given that the perimeter is 24 cm, we can set up the equation:

24 = 2 * (2b + 2)

Now, let's solve for 'b' to find the width of the rectangle:

24 = 4b + 4

4b = 24 - 4

4b = 20

b = 20 / 4

b = 5

So, the width of the rectangle is 5 cm.

To find the length, we can substitute the value of 'b' back into the expression for 'a':

a = b + 2

a = 5 + 2

a = 7

Therefore, the length of the rectangle is 7 cm.

In summary, the length of each side of the rectangle is 7 cm for the longer side and 5 cm for the shorter side.
