Infinitely many.
No, because there are an infinite number of such shapes. In fact, there are an infinite number of triangles with a perimeter of 12 cm.
Depends on the arrangement. ^^^^ would be 12 units squared

There are many different triangles with a base of 10 km and height of 12 km, and they have different perimeters. The smallest perimeter occurs if the third vertex is directly above the midpoint of the base; then the altitude from that vertex divides the triangle into two congruent triangles with sides 5, 12, and (by the Pythagorean theorem) 13. The sides of length 12 are shared, so the perimeter of the triangle is 36 km in this case. If the third vertex is moved to one side but kept at the same height, the perimeter increases; there is no upper bound on the perimeter that can be achieved.

There are 12 triangles in 2 hexigons
It is necessary to mention that the two triangles are similar.Let the perimeter of the triangle MNP be x cm.Since the triangles XYZ and MNP are similar triangles,8/12 = x/80 (multiply both sides by 80)640/12 = x53.3333... = x53 3/9 = x53 1/3 = xThus, the perimeter of the triangle MNP is 53 1/3 cm.
