A Saree Is 5 M Long And 13 M Wide. A Border Of Width 25 cm is printed along its sides. Find The Cost Of Printing The Border At Rs 1 Per 10 Cm2.

Sol:

The area of border = Area of the saree – Area of the unborded saree

= (500 * 130) – (500 – 2 * 25) * (130 – 25 * 2)

= (65000) – (500 – 50) * (130 – 50)

= (65000) – (450) * (80)

= 65000 – 450 * 80

= 65000 – 36000

= 29000 cm^{2}

Cost = Area * Rate

= \( 29,000 *  \frac{1}{10} \frac{Rs}{Cm^{2}}\)

= Rs.2,900

Therefore, the cost of printing the border at Rs.1 per 10 cm2 is Rs.2,900.
