A) Step-by-step algorithm and flowchart
B) Diagram of the four walls
C) Calculation of total area
D) None of the above

Answer 1

The area of four walls with the formula a=2H(L+B) is:

A) Step-by-step algorithm and flowchart

Step-by-step explanation:

To find the area of four walls using the formula
`\( a = 2H(L+B) \)`, the algorithm and flowchart are designed as follows:

1. Input: Obtain the values for height (H), length (L), and breadth (B).

2. Calculate: Use the formula
`\( a = 2H(L+B) \)` to find the area of one wall.

3. Multiply: Multiply the result by 4 to get the total area of four walls.

4. Output: Display the total area.

The flowchart visually represents these steps, ensuring a clear and systematic approach to computing the area of four walls. It starts with inputting the necessary values, proceeds to the calculation using the specified formula, and finally outputs the total area. This algorithm and flowchart provide an efficient and organized method for determining the surface area of four walls, facilitating easy implementation in programming or manual calculations.
