Question
What is the cost of painting a wall with a length of 15 m and abreadth of 20 m if the cost of painting is Rs. 10 per m²?
Solution
To calculate the cost of painting the wall, we first need to find the area of the wall.
Step 1: Calculate the area of the wall The area of a rectangle (which in this case is our wall) can be calculated using the formula: Area = length x breadth So, the area of the wall = 15 m x 20 m = 300 m²
Step 2: Calculate the cost of painting The cost of painting is given as Rs. 10 per m². Therefore, to find the total cost of painting the wall, we multiply the area of the wall by the cost per m². So, the cost of painting = Area of the wall x Cost per m² = 300 m² x Rs. 10/m² = Rs. 3000
Therefore, the cost of painting a wall with a length of 15 m and a breadth of 20 m is Rs. 3000.
