Calculation of the Cost of Painting a Door

To calculate the cost of painting a door, we need to consider the cost of paint and the cost of the painter's service. Given the following information:

- Cost of 1 kg of paint: 100 rubles- Cost of painter's service per square meter: 200 rubles- Width of the door: 2 meters - Length of the door: 1 meter - Number of doors in the house: 5 - Cost of paint per square meter: 50 rubles Let's break down the calculation step by step:

1. Calculate the area of one door: - Area = Width x Length = 2 meters x 1 meter = 2 square meters

2. Calculate the cost of paint for one door: - Cost of paint for one door = Area x Cost of paint per square meter = 2 square meters x 50 rubles = 100 rubles

3. Calculate the cost of painting all the doors: - Cost of painting all the doors = Cost of paint for one door x Number of doors = 100 rubles x 5 = 500 rubles

4. Calculate the cost of the painter's service for all the doors: - Cost of painter's service for all the doors = Cost of painter's service per square meter x Area of one door x Number of doors = 200 rubles x 2 square meters x 5 = 2000 rubles

5. Calculate the total cost of painting the doors: - Total cost of painting the doors = Cost of painting all the doors + Cost of the painter's service for all the doors = 500 rubles + 2000 rubles = 2500 rubles

Therefore, the total cost of painting the doors would be 2500 rubles.

Please note that the above calculation is based on the provided information and assumptions. The actual cost may vary depending on various factors such as the type of paint used, additional services required, and local market rates.
