Depends on the arrangement. ^^^^ would be 12 units squared
To calculate the perimeter of four triangles fitted together, first determine the lengths of all the external sides that form the outer boundary of the configuration. Add these lengths together to find the total perimeter. If any sides of the triangles are shared or internal, do not include these in the perimeter calculation. Ensure that the triangles are arranged in a way that their outer edges are clearly defined for accurate measurement.
Three: 2, 5, 5 3, 4, 5 and 4, 4, 4
the answer to this question is 1:4 10: ? =10x4/1 =40
They don't always- they don't always 'has' a smaller perimeter than other triangles. A triangle can be absolutely any size as long as it has three sides and angles that add to 180 degrees
Infinitely many.

two isosceles triangles with common line
When two triangles can form a square, it is often referred to as "triangular tiling" or "triangular decomposition." This concept is commonly seen in geometry, where right triangles can be arranged in such a way that their combined area equals that of a square. In particular, if the triangles are right triangles, they can be arranged to fit perfectly within the square's boundaries.
you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
An infinite number are possible.
The perimeter of any triangle is the sum of its 3 sides
You can't tell. There are an infinite number of triangles that all have a perimeter of 144.
