Question

Find the cost of fencing a square park of side 105 m at the rate of ₹30 per metre​

Answer 1

Answer:

[tex]Perimeter of square park =4×Side

Here, 

Side =250 m

Perimeter of square park =4×105

                                           = 420m

Cost of fencing of the park at the rate Rs.20 per meter =420×20

                                                                                             8400

Answer 2

Answer:

₹12,600

Step-by-step explanation:

Perimeter of square = 4a, where a is the side

So, 4 * 105 = 420

Cost of 1 metre of fence = ₹30

So, cost of 420m of fencing = 30 * 420

= ₹12,600
