Final answer:
An algorithm to find the perimeter of rectangle is:
1) Define the width of the rectangle.
2) Define the Height of the rectangle.
3) Define perimeter of the rectangle.
4) Calculate the perimeter of the rectangle by applying the formula P = 2l + 2w.
5) Assign the perimeter of the rectangle to the area variable.
6) Print the perimeter of the rectangle.
Step-by-step explanation:
The formula for the perimeter (P) is P = 2l + 2w, where ‘l’ is the length and ‘w’ is the width of the rectangle.

For example: Below is the step by step descriptive logic to find perimeter of a rectangle in 'C' language:
- Input length and width of the rectangle using scanf() function.
- Store it in two variables say length and width.
- Calculate perimeter using formula for perimeter of rectangle perimeter = 2 * (length + width).
- Print the value of perimeter.
