Convert the algorithms of questions 4 to 9 into flowcharts.

Flowchart 4: Calculate the Area of a Rectangle

1. Start
2. Input Length (L)
3. Input Breadth (B)
4. Calculate Area = L × B
5. Display Area
6. End

Flowchart Structure:

• Start → Input Length (L) → Input Breadth (B) → Calculate Area → Display Area → End

Flowchart 5: Convert Inches to Centimeters

1. Start
2. Input Length in Inches
3. Convert to Centimeters = Inches × 2.54
4. Display Centimeters
5. End

Flowchart Structure:

• Start → Input Length in Inches → Convert to Centimeters → Display Centimeters → End

Flowchart 6: Check if a Student Passed or Failed

1. Start
2. Input Marks
3. Is Marks ≥ 33?
   • If Yes, go to step 4
   • If No, go to step 5
4. Display “PASS”
5. Display “FAIL”
6. End

Flowchart Structure:

• Start → Input Marks → Decision (Is Marks ≥ 33?) → [Yes] → Display “PASS” → End
• Start → Input Marks → Decision (Is Marks ≥ 33?) → [No] → Display “FAIL” → End

Flowchart 7: Sum of a Sequence of Numbers

1. Start
2. Initialize Sum = 0
3. Add 20 to Sum
4. Add 25 to Sum
5. Add 30 to Sum
6. Add 35 to Sum
7. Add 40 to Sum
8. Add 45 to Sum
9. Add 50 to Sum
10. Add 55 to Sum
11. Add 60 to Sum
12. Display Sum
13. End

Flowchart Structure:

• Start → Initialize Sum = 0 → Add 20 → Add 25 → Add 30 → Add 35 → Add 40 → Add 45 → Add 50 → Add 55 → Add 60 → Display Sum → End

Flowchart 8: Product of a Sequence of Numbers

1. Start
2. Initialize Product = 1
3. Multiply Product by 1
4. Multiply Product by 3
5. Multiply Product by 5
6. Multiply Product by 7
7. Multiply Product by 9
8. Multiply Product by 11
9. Multiply Product by 13
10. Multiply Product by 15
11. Display Product
12. End

Flowchart Structure:

• Start → Initialize Product = 1 → Multiply Product by 1 → Multiply Product by 3 → Multiply Product by 5 → Multiply Product by 7 → Multiply Product by 9 → Multiply Product by 11 → Multiply Product by 13 → Multiply Product by 15 → Display Product → End

Flowchart 9: Print Multiplication Table in Reverse Order

1. Start
2. Input Number (N)
3. For i = 10 down to 1
   • Multiply N × i
   • Display the result
4. End

Flowchart Structure:

• Start → Input Number (N) → Loop (For i = 10 down to 1) → Multiply N × i → Display Result → End
