Question

A saree is 5 m long and 1.3 m wide. A border of width 25 cm is printed along its sides. Find
the cost of printing the border at * 1 per 10 cm².​

Answer 1

Answer:

l=500cm

w=130cm

now the area of entire saree is A= 500*130=65000 cm²

now to find the area of the border, we should subtract the area of the middle of the saree from the whole area. Firstly, let's find the area of the middle part of saree,  where length= 500- 25 - 25 =450 cm and width= 130 - [25*2] = 80cm.

so, the area of the middle part = B = 450*80 = 36000 cm²

[you can check the diagram I drew if you get confused]

that means, the area of the border of the sari is A-B= 65000-36000=29000cm²

now the cost is Rs.1 per 10 cm², which means for 29000 cm² it is...

➣ 29000/10 = 2900 Rs.
