the formula perimeter depends upon the shape of the figure .
The perimeter of rectangle = 2 X( l + b).
perimeter of triangle = sum of all sides .
perimeter of square = 4 X side .
perimeter of circle = 2 X pi x r .
Depends on what information you have and what you require. If you have all three sides, there are different formulae to find the perimeter, angles and area. If you have two sides and an angle (depending on the angle) you have formulae for the remaining side and then perimeter and area. If you have a side and two angles there are formulae to find the missing sides and then perimeter and area. There are other possibilities: you have the altitude and require the area; etc.
There are different formulae for calculating the lengths of the sides or altitudes, medians, etc; the measure of angles, the perimeter and area. Furthermore, these depend on the information available.There are different formulae for calculating the lengths of the sides or altitudes, medians, etc; the measure of angles, the perimeter and area.

Perimeter: Add up the length of all the sides. Area: You have to learn formulae for different figures, and apply them. For a rectangle, you just multiply length x side. For other figures, use other formulae. For example, the area of a triangle is 1/2 x base x height (where the height is perpendicular to the base).
What does '136',7 cm' represent??? The perimeter, a side, or a diagonal. Please clarify.
You will find several formulae in the Wikipedia article on "derivative".
