Sum of lengths bounding the shape = 100 cm.
Without information about the shape it is impossible to say anything further than that. In a very few exceptional cases, the length of individual sides can be determined as well as the area. But in order to do that it is necessary to know what equation is required. There is no THE equation.
In the majorrity of cases, though, there is no direct relationship between the perimeter and the area or lengths of sides.

Area of a square = side^2 10,000 = side^2 100 = side Perimeter = 4(side) = 4 x 100 = 400 cm
Let the breadth be x and the length be x+20 So: 2*(x+x+20) = 100 => 4x+40 = 100 => 4x = 100-40 => 4x = 60 => x = 15 The dimensions are: length = 35 cm and breadth = 15 cm Check for perimeter: 2*(35+15) = 100 cm
40 cm Perimeter = 2 L + 2W = 30 + 10
The length could be 3 cm (width = 1 cm), with a perimeter of 8 cm, which is not more than 72 cm. Or it could be 6 cm (w = 2 cm, perimeter = 16 cm).
Perimeter of rectangle = 2 x ( L + W ) = 2 x 64 = 128 cm. or Perimeter of rectangle = 2L + 2W = 68 + 60 = 128 cm.
