Question

3. Find the expenditure of putting a barbed wire around a 4 hectare square field, if it cost ₹45 per
meter?​

Answer 1

Step-by-step explanation:

Area of square shaped farm=4 hectares

10,000 m^2 (1 hectare =10,000 sq m)

Hence area of farm =40,000 square meters

Area of square =(side)^2

(side)^2 =40,000

side =root 40,000

side =200m

perimeter of square =4(side)

4×200

800

Given cost of fencing is Rs 45 per meter

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