the cost of printing the border at 31 per 10 cm².​

Answer 1

Step-by-step explanation:

1. area = 5 *1.3*25 = 162.5
2. 1cm^2 = 31/10=3.1. 162.5 cm^2 *3.1= 1015/4

Answer 2

Answer:

cost=(29000/10)×1=rs2900

Step-by-step explanation:

1. Length of saree=5m =500cm
2. Breadth of saree =1.3m=130cm
3. Area of saree with border=500×130=65000cm2
4. Now length of saree without borders=500-(25+25)=450cm
5. Breadth of saree without borders=130-(25+25)=80cm
6. Area without borders=450×80=36000cm2
7. Area of border=65000-36000=29000cm2

cost=(29000/10)×1=Rs 290
