a saree is 5 meter long and 1.3 meter wide. a border of width 25 centimeter is printed along all side .find the cost of printing the border at 1rupees per 100 centimeter2.
Hi Ayush!
Here is the solution to your question
Length of the saree = 5 m = 500 cm
Width of the saree = 1.3 m = 130 cm
Total area of the saree = 500 × 130 cm2 = 65000 m2
Width of the border = 25 cm
Length of the saree excluding border = (500 – 25 – 25) cm = 450 cm
Width of saree excluding the border = (130 – 25 – 25) cm = 80 cm
Area of saree excluding the border = 450 × 80 cm2 = 36000 cm2
Area of the border = total area of saree – area of saree excluding the border
= (65000 – 36000) cm2
= 29000 cm2
Cheers!
