Question

Find the expenditure of putting a barbed wire around a 4hecter square field if it costs 45 per meter

Answer 1

45 per meter . Therefore, the total cost of fencing for 800 mof barbed wire is the product of the total length of the field and cost of fencing per square meter. C = 45×800 = Rs. 36,000.

Answer 2

Question

Find the expenditure of putting a barbed wire around a 4hecter square field if it costs 45 per meter

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
