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 ..
