Answer 2

Answer:

The cost of fencing a square park of side 100 m at the rate of ₹ 20 per meter is ​₹8000

Step-by-step explanation:

Here we are provided with a square field whose one side is 100 m and we have been asked to find the cost of fencing this square field if the cost of fencing is ₹20 per meter.

so to find the cost of fencing the square field we have to find the  perimeter of the square park

we know that,

The perimeter of square= 4×side

                                = 4×100m

                                  = 400m

rate of fencing one meter = ₹20

∴ Rate of fencing 400 m = ₹( 400×20)

                                       =₹ 8000

Hence the cost of fencing a square park of side 100 m at the rate of ₹ 20 per meter​ is ₹8000.
