A saree is 5 m long and 1.3 m wide . A border of width25 cm is pritedalong its sides. Find the costofprinting the border at rs 1 per 10 cm sq.
The area of the border is
(5*1.3) - (5-0.5)(1.3-0.5) = 2.9 m^2
so the cost is
2.9m^2 * (100cm/1m)^2 * rs1/10cm^2 = rs 2900
2900
2900
To find the cost of printing the border, we need to determine the area of the border and then calculate the cost based on the given rate.
First, we need to calculate the area of the border. The width of the border is given as 25 cm. However, we need to convert the width into meters to match the measurements of the saree.
Converting 25 cm to meters:
25 cm = 25/100 meters = 0.25 meters
Next, we need to calculate the length of the border. Since the border is printed along both sides of the saree, we multiply the width by 2.
Length of the border = 1.3 m (width) * 2 = 2.6 m
Now, we can calculate the area of the border:
Area of the border = Length * Width
= 2.6 m * 0.25 m
= 0.65 square meters
To calculate the cost, we need to convert the area from square meters to square centimeters because the rate is given in rupees per 10 square centimeters.
Converting the area from square meters to square centimeters:
0.65 square meters = 0.65 * (100 * 100) square centimeters
= 65,000 square centimeters
Finally, we can calculate the cost of printing the border:
Cost = Area of the border * Rate
= 65,000 square centimeters * (1 rupee / 10 square centimeters)
= 6500 rupees
Therefore, the cost of printing the border at a rate of 1 rupee per 10 square cm is 6500 rupees.
