A saree is 5m long and 1.3m wide .A border of width 25cm us printed along its sides . Find the costs of printing the border at Re 1per 100cm square.
Long answer
A intersting question
To find the cost of printing the border on the saree, we need to first calculate the area of the printed border and then calculate the cost based on the given rate.
The saree is 5m long and 1.3m wide. Since the border is printed along the sides, it means the length of the border will be the same as the length of the saree, which is 5m.
The width of the border is given as 25cm. To calculate the area of the border, we need to convert the length and width to the same units. Let's convert the width to meters.
1 meter = 100 centimeters, so 25 cm = 25/100 = 0.25 meters.
Now, we can calculate the area of the border:
Area of the border = Length × Width
= 5m × 0.25m
= 1.25 square meters
To calculate the cost, we need to convert the area from square meters to square centimeters because the rate is given in Re 1 per 100 square centimeters.
1 square meter = 10,000 square centimeters
1.25 square meters = 1.25 × 10,000 = 12,500 square centimeters
Finally, we can calculate the cost:
Cost = Area of the border × Rate per 100 square centimeters
= 12,500 square centimeters × Re 1/100 square centimeters
= Rs. 125
Therefore, the cost of printing the border on the saree is Rs. 125.
Very good and very good explanation and very long
the area of the border is
(500)(130)-(500-2*25)(130-2*25) = 29000 cm^2
Now you can find the cost
