Question

Find the cost of facing a square park of side 100m at the rate of 40 rupees per meter​

Answer 1

Answer:

Rs 1600

Step-by-step explanation:

Length of side of square park = 100 m

Boundary of park = Perimeter of park = 4 * side

                                                              = 4 * 100

                                                              = 400 m

Cost of fencing 1 meter = Rs 40

Cost of fencing park = Rs 40 * boundary of park

                                  = Rs 40 * 400

                                  = Rs 1600

Hope my answer helped you.

Answer 2

Answer: Rs. 16000

Step-by-step explanation:

Side of a square park = a = 100m

Perimeter of park = 4a

                             = 4 X 100

                             = 400m.

Cost of fencing 1m square park = Rs. 40

Cost of fencing 1000m square park = 40 X 400

                                                           = Rs. 16,000
