Answer:
The Basic Program is as follows:
10 LENGTH = 50
15 WIDTH = 30
20 AREA = WIDTH * LENGTH
25 PRINT AREA
30 END
The Algorithm is as follows:
1. Start
2. Let Length = 50
3. Let Width = 30
4. Compute Area = Length * Width
5. Display Area
6. Stop
See Attachment for flowchart (flowchart is designed using draw io tools)
Step-by-step explanation:
The flowchart, algorithm and basic program all follow the same sequence and explanation
Using the basic program as a case study;
Line number 10: The program starts by initializing LENGTH to 50
Line number 15: It then initializes WIDTH to 30
Line number 20: The AREA is calculated by LENGTH * WIDTH
Line number 25: The value of AREA is printed afterwards
Line number 30: Lastly, the program stops execution
