1 hectare = 10000 sq metre

2 hectare = 20000 sq metre

acc. to the question

let the breadth and the length of the rectangular field be x and 2x

area of rectangular field= length*Breadth

20000 = 2x*x

20000=2x sq

20000/2=x sq

10000=x sq

√10000=x

x=100 metre

so, length=2*100

=200 metre

cost of fencing the field at ₹50 per metre = 20000*50

= 1000000 rupees
