Question

Периметр прямоугольника 14 см а ширина на 3 см меньше длины Начерти этот прямоугольник

Answer 1

В общем, решается всё простым уравнением:
14=(х+х+3)×2
14=4х+6
8=4х
х=2
Это ширина.
А длинна будет равняться 2+3=5
В итоге, вы должны нарисовать прямоугольник с динной 5см и шириной 2см.

Answer 2

Calculation of the Perimeter of a Rectangle

To calculate the perimeter of a rectangle, we need to know the length and width of the rectangle. In this case, the width is given as 3 cm less than the length, and the perimeter is given as 14 cm.

Let's denote the length of the rectangle as L and the width as W. According to the given information, we have the following equations:

1. W = L - 3 (The width is 3 cm less than the length) 2. 2(L + W) = 14 (The perimeter is 14 cm)

To find the values of L and W, we can solve these equations simultaneously.

Solving the Equations

Substituting the value of W from equation 1 into equation 2, we get:

2(L + (L - 3)) = 14

Simplifying the equation:

2(2L - 3) = 14 4L - 6 = 14 4L = 20 L = 5

Now, substituting the value of L into equation 1, we can find the value of W:

W = 5 - 3 W = 2

Therefore, the length of the rectangle is 5 cm and the width is 2 cm.

Drawing the Rectangle

To draw the rectangle, we can use the given length and width. The length is 5 cm and the width is 2 cm. Here is a representation of the rectangle:

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

Please note that the dimensions of the rectangle are not to scale in this representation.

Conclusion

The perimeter of the rectangle with a length of 5 cm and a width of 2 cm is 14 cm.
