Answer:

Step-by-step explanation:

TOTAL PERIMETER OF CIRCLE-22\7*2*3

                                                    18.84 METER

PERIMETER OF SECTOR WITH ANGLE 90 DEGREES-            2*90\360*2*22\7*3

9.42 METER

PERIMETER OF REMAINING CIRCLE-  (18.84-9.42)+2*3

                                                               =15.42 meters

HOPE THIS IS HELPFUL...
