What is the length of outer boundary of the park shown in the given figure? What will be the total cost of fencing it at the rate of Rs 20 per metre?
Length of outer boundary = Perimeter of park = Sum of all sides length = (200 + 300 + 80 + 300 + 200 + 260) m = 1340 m
Also, the rate of fencing per metre = Rs 20
Then, the rate of fencing 1340 metre = 20 × 1340 = Rs 26800
