Draw different rectangles with the perimeter of 12 units

3x3

2x4
1x5

and, if you don't need integers,

2.5 x 3.5
1.7 x 4.3
etc, as long as length+width=6

To draw different rectangles with a perimeter of 12 units, you need to consider that the perimeter of a rectangle is calculated by adding the lengths of all its sides.

Let's explore a few possibilities:

1. Rectangle with sides measuring 3 units and 3 units:
- Side 1: 3 units
- Side 2: 3 units
- Side 3: 3 units
- Side 4: 3 units
This rectangle will have a perimeter of 12 units.

2. Rectangle with sides measuring 2 units and 4 units:
- Side 1: 2 units
- Side 2: 4 units
- Side 3: 2 units
- Side 4: 4 units
This rectangle will also have a perimeter of 12 units.

3. Rectangle with sides measuring 1 unit and 5 units:
- Side 1: 1 unit
- Side 2: 5 units
- Side 3: 1 unit
- Side 4: 5 units
Again, this rectangle will have a perimeter of 12 units.

You can continue this pattern by using different combination of side lengths that add up to 12 units, such as 1, 1, 2, and 8 units or 4, 1, 4, and 3 units. By varying the lengths of each side length, you can create a variety of rectangles with a perimeter of 12 units.
