Explanation

This is the correct answer. The total cost of fencing is Rs. 7200. The rate of fencing is Rs. 12/m.

Perimeter x rate of fencing = total cost Perimeter = total cost/rate = 7200/12 = 600 m Length = 175  Breadth = ? Perimeter = 600 P = 2(L + B) 600 = 2(175 + b) = 350 + 2b 600 - 350 = 2b 250 = 2b b = 250/2 = 125 m
