Answer 2

Answer:

Rs 42,000

Step-by-step explanation:

as, area of square field = 9 hectares

as 1 hectare = 10,000m²

so area of square field = 90,000m²

so, a² = 90000

a = 300m

where a is the side of square field...

so if Rs 35 per metre is the cost of fencing the square field...

then total cost = 35×4a

= 35×4×300

= Rs 42,000 ..... ans.
