Perimeter = 2 x (width + length)⇒ 12 = 2 x (width + length)⇒ width + length = 6⇒ the rectangles could be:1 by 52 by 43 by 3[A square is a rectangle with equal sides.]
There are an infinite number of rectangles with this perimeter. The "whole number" sides could be (5 x 1), (4 x 2) or (3 x 3), but (5½ x ½) or (3¼ x 2¾) etc would fit the description.
Yes, I could draw three rectangles with 12 units, so long as the perimeter of the rectangles sum up to 12. You're probably asking for integer lengths, though. A square is a special type of rectangle where all the sides are the same length, so I could have 3 squares with a side length of 1 unit, which gives 3x(1x4)=12 units.
A right angled triangle with sides 3,4 and 5 units and a square with each side = 3 units.

Rectangles with a perimeter of 20 units can have various dimensions, as long as the sum of the lengths of all four sides equals 20 units. One example could be a rectangle with sides measuring 4 units by 6 units, as 4 + 4 + 6 + 6 = 20. Another example could be a square with sides measuring 5 units each, as 5 + 5 + 5 + 5 = 20. In general, rectangles with sides of any length that add up to 20 units can have a perimeter of 20 units.

Assuming you mean that you you have two SIMILAR triangles and the areas are related by the ratio 1:4, then you are wanting to know the ratio of the side lengths: ratio areas = ratio sides² → ratio sides = √ ratios area = √1 : √4 = 1 : 2 The side lengths of the SIMILAR triangle which has 4 times the area of the other has side lengths that are twice the length of the other.
To determine if the ratio of length to width for two rectangles is proportional, you need to compare the ratios of their lengths to widths. If the ratios are equal, then the rectangles are proportional. For example, if Rectangle A has a length of 10 units and a width of 5 units (ratio of 10:5 or 2:1), and Rectangle B has a length of 20 units and a width of 10 units (ratio of 20:10 or 2:1), then the rectangles are proportional because the ratios are equal.
