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.

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.
Given side lengths of 8 units, an equilateral triangle will have an altitude of 7 (6.9282) units.

The perimeter of an isosceles triangle can vary based on the lengths of its sides. For example, if the two equal sides each measure 5 units and the base measures 6 units, the perimeter would be 5 + 5 + 6 = 16 units. Alternatively, if the two equal sides are 7 units each and the base is 4 units, the perimeter would be 7 + 7 + 4 = 18 units. Thus, possible perimeters can be 16 units and 18 units.

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.
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.
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.
