Question

Периметр прямокутника 24см Ширина9см.Знайди довжину прямокутника.Накресли даний прямокутник.

Answer 1

24=2х(9+х)
24=18+2х
24-18=2х
6=2х
х=6:2
х=3

Answer 2

Р=(а+b)×2
24=18+2b
2b=6
b=3 длина прямоугольника

Answer 3

Perimeter of a Rectangle

To find the length of a rectangle when given its width and perimeter, we can use the formula for the perimeter of a rectangle:

Perimeter = 2 * (Length + Width)

In this case, we are given that the perimeter of the rectangle is 24 cm and the width is 9 cm. Let's substitute these values into the formula and solve for the length.

24 = 2 * (Length + 9)

To isolate the length, we can start by dividing both sides of the equation by 2:

12 = Length + 9

Next, we can subtract 9 from both sides of the equation:

Length = 12 - 9

Simplifying further:

Length = 3 cm

Therefore, the length of the rectangle is 3 cm.

Drawing the Rectangle

To draw the rectangle, we can use the given dimensions of the width (9 cm) and length (3 cm). Here is a simple representation of the rectangle:

   -----------------
   |               |
   |               |
   |               |
   |               |
   -----------------

The horizontal sides represent the width of 9 cm, and the vertical sides represent the length of 3 cm.
