The following rectangles all have perimeters of 12:
1 by 5
1.2 by 4.8
1.4 by 4.6
1.6 by 4.4
1.8 by 4.2
2 by 4
2.3 by 3.7
2.5 by 3.5
2.8 by 3.2
3 by 3
There are an infinite number more.

Given side lengths of 8 units, an equilateral triangle will have an altitude of 7 (6.9282) units.
3.1 and 2.9 units 3.2 and 2.8 units 3.3 and 2.7 units etc or 3.01 and 2.99 units 3.02 and 2.98 units 3.03 and 2.97 units etc. All you need to do is to have two different postitve numbers that sum to 6 (half of 12)
Perimeter is the length around the object, so it is a linear quantity. For n sided figures, you add the lengths of the n sides. Multiplication would give you units of area.

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.
perimeter
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.
An 8x8 rectangle is either a square, all of whose sides are 8 units long or it can be a rectangles whose opposite sides are 8 units long - but in different measurement units: for example, a rectangle whose sides are 8 centimetres and 8 metres.
A collection of squares and rectangles with different coloured sides that are used to represent units and variables.
