A banner 3.5 m and long 2 m wide is painted on a cloth such that there...
The Problem:
We have a banner that is 3.5 m long and 2 m wide. The banner is painted on a cloth with a margin of 1.5 cm along each of its sides.
The Solution:
To find the total cost of painting the banner, we need to calculate the area of the banner and then multiply it by the cost per square meter.
Step 1: Calculate the area of the banner:
The actual length and width of the banner, excluding the margins, can be calculated by subtracting twice the margin width from the given dimensions.
Actual length = 3.5 m - 2 * 0.015 m = 3.47 m
Actual width = 2 m - 2 * 0.015 m = 1.97 m
The area of the banner can be calculated by multiplying the actual length and width:
Area of the banner = Actual length * Actual width = 3.47 m * 1.97 m = 6.829 m²
Step 2: Calculate the total cost of painting:
The cost of painting is given as Rs 10 per square meter. We can calculate the total cost by multiplying the area of the banner by the cost per square meter.
Total cost of painting = Area of the banner * Cost per square meter = 6.829 m² * Rs 10/m² = Rs 68.29
Conclusion:
The total cost of painting the banner is Rs 68.29.
