find the expenditure of putting a barbed wire around a 4 hectare squar

1.	find the expenditure of putting a barbed wire around a 4 hectare square field, if it costs Rs 45 per metre
Answer» Area of square shaped farm = 4 hectares = 10,000 m² [1 hectare = 10,000 sq m] Hence area of farm = 40,000 square meters. Area of square = (side)² (side)² = 40,000 side = √40000 side = 200 m Perimeter of square= 4(side) 4 × 200m 800 Given cost of fencing is Rs. 45 per meter Hence total cost for fencing 800 m= 45 × 800 = Rs. 36,000 thanks

find the expenditure of putting a barbed wire around a 4 hectare square field, if it costs Rs 45 per metre

Answer»

Area of square shaped farm = 4 hectares

= 10,000 m² [1 hectare = 10,000 sq m]

Hence area of farm = 40,000 square meters.

Area of square = (side)²

(side)² = 40,000

side = √40000

side = 200 m

Perimeter of square= 4(side)

4 × 200m

800

Given cost of fencing is Rs. 45 per meter

Hence total cost for fencing 800 m= 45 × 800 = Rs. 36,000
