It is the sum of the lengths of its sides.
Add the lengths of the three individual sides.
The answer depends on what information you have but, basically, you need to add together the lengths of the three sides of the triangle.
Just add each of the three lengths of the triangle together. In an equilateral triangle, all side are the same. In an isosceles, 2 sides are the same and one is different.
Several solutions are possible here. The four sides could be the same length, or different lengths. The only requirement (with respect to lengths) to be called an "isosceles trapezoid" is that two opposite sides have the same length.Several solutions are possible here.

Lengths of: equal side+equal side+base = perimeter
Add the lengths of the three individual sides.

There is only one equilateral triangle with a perimeter of 60 units. Its side lengths are integers.
Isosceles triangles are triangles in which two of the three sides have different lengths.
I don't see any isosceles triangle below.In general, the perimeter is the sum of the lengths of all sides. Note that in an isosceles triangle, two of the three sides have the same length.
The perimeter of a dodecagon is the sum of the lengths of its 12 sides. These sides may be of different lengths.
