name the lengths of the sides os three rectangles with the perimeters of 12 units. Use only hole numbers

1 and 6

2 and 3

Forget that. That's for area.

1 and 5

3 and 3

To find the lengths of the sides of three rectangles with a perimeter of 12 units using only whole numbers, we can start by considering the possible combinations of lengths.

Let's list out all the possibilities:

Option 1:
Length = 1 unit
Width = 5 units
Perimeter = 2(Length + Width) = 2(1 + 5) = 2(6) = 12 units

Option 2:
Length = 2 units
Width = 4 units
Perimeter = 2(Length + Width) = 2(2 + 4) = 2(6) = 12 units

Option 3:
Length = 3 units
Width = 3 units
Perimeter = 2(Length + Width) = 2(3 + 3) = 2(6) = 12 units

These are the three possible combinations of lengths and widths for rectangles with a perimeter of 12 units, using only whole numbers.
