Question 40

Total cost of fencing the park shown in the given figure is ₹55000. Find the cost of fencing per metre.

Answer 1

Perimeter of ABCDEFA = Sum of all sides

= AB + BC + CD + DE + EF + FA

= (150 + 100 + 120 + 180 + 270 + 280)m = 1100 m

Total cost = ₹ 55000 [given]

Now, cost of fencing per metre = $\frac{\text{Total cost}}{\text{Perimeter}}=\frac{55000}{1100}=₹50$
