Question

saree is 5 metre long and 1.3 metre wide a border of width 25 cm is printed along its sides . find the cost of printing the border at rupees 1 per cm2​

Answer 1

Length of saree = 5 m = 500 cm

Breadth of saree = 1.3 m = 130 cm

Area of saree with border = 500×130 = 65000 cm²

Now, length of saree without border = 500 - (25+25) = 450 cm

Breadth of saree without border = 130 -(25+25) = 80 cm

Area without border = 450×80 = 36000 cm²

Area of border = 65000 - 36000 = 29000 cm²

Cost = (29000/10)×1 = Rs 2900

Answer 2

$\huge \purple {AnsWer}$

Length = 5m

Breath = 1.3m

Area ( Outer ) = L × B

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 5 × 1.3 = 6.5m²

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 6.5 × 100 × 100

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 65000 m.

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Area of inner = L × B

⠀⠀⠀Length ( I ) = 5 - 50 = 4.50 × 100

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 450 cm.

⠀⠀⠀Breadth ( I ) = 1.3 - 50 = 80 × 100

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 80 cm.

⠀⠀⠀⠀⠀⠀⠀⠀⠀

A = L × B = 450 × 8

⠀⠀⠀⠀⠀⠀= 36000.

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Area of Border = Outer area - Inner area

⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 65000 - 36000

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 29000 cm².

Total cost = Area × Cost per cm²

⠀⠀⠀⠀⠀⠀⠀$= 29000 \times \frac{1}{2}$

⠀⠀⠀⠀⠀⠀⠀= ₹2900 ..
