Please show all the steps

Answer 1

Answer:

Perimeter is 132 m and costs Rs.528 for fencing...

Step-by-step explanation:

Diameter of garden=21m

Radius of garden=21/2 m

Perimeter/Circumference of circle=2πr

                                                        =2*22/7*21/2

                                                        =22/7*21

                                                        =22*3

                                                        =66m

Rope needed for two rounds=66*2

                                                =132m

cost per meter= Rs.4

Total Cost= 132*4

                =  Rs.528
