65cm×40cm = 2600cm

100cm =1m

2600cm÷100=26m

26m×20rs=520Rs

I hope this right answer

Answer 2

it seems mistake in question ,I think cost of aluminium is Rs 20 per square centimeter.

dimensions of rectangle sheet

length = 65cm , breadth = 40cm

area of rectangular sheet

= length × breadth

= 65 × 40 =2600cm^2

cost of 1cm^2 = Rs20

cost of 2600cm^2 = 2600 × 20

= Rs52000

Answer:
_______
cost of aluminium sheet = Rs52000
