Question

Составьте блок схему и напишите программу. Длина прямоугольного участка земли равна Х метров, а ширина равна Y метров .Напишите программу вычисления количества досок для забора на заданном участке , если ширина доски равна 10 сантиметров

Answer 1

Program skor_d;var a,b,c: real ;beginwriteln('Введите длину '); read(a);writeln('Введите ширину'); read(b);c:=a*b;c:=c*100;writeln('потребуется досок ',c/10);end.

Answer 2

Program to Calculate Number of Boards for a Fence

To calculate the number of boards needed for a fence on a given rectangular piece of land, we can use the following program:

def calculate_number_of_boards(length, width, board_width_cm):
    # Convert length and width to centimeters
    length_cm = length * 100
    width_cm = width * 100
    
    # Calculate perimeter in centimeters
    perimeter_cm = 2 * (length_cm + width_cm)
    
    # Calculate number of boards needed
    number_of_boards = perimeter_cm / board_width_cm
    
    return number_of_boards

# Input values
length_meters = float(input("Enter the length of the land in meters: "))
width_meters = float(input("Enter the width of the land in meters: "))
board_width_cm = 10  # Width of the board in centimeters

# Calculate and print the number of boards needed
print("Number of boards needed:", calculate_number_of_boards(length_meters, width_meters, board_width_cm))

This program takes the length and width of the land in meters and the width of the board in centimeters as input, calculates the number of boards needed for the fence, and then prints the result.

Explanation

- The program first converts the length and width from meters to centimeters to ensure consistent units for calculation. - It then calculates the perimeter of the land in centimeters, which is the total length of the fence required. - The number of boards needed is calculated by dividing the perimeter by the width of each board in centimeters. - The result is then printed as the number of boards needed for the fence.

Feel free to run this program with your specific values for the length and width of the land to calculate the number of boards needed for the fence.
