Side = 44 dm = 440 cm
Perimeter = 3(440) = 1320 cm
Perimeter of the Circle will be equal to the perimeter of triangle because they are made from the same wire .
So,
2πr = 1320
2 x 22/7 x r = 1320
r = 1320 x 1/2 x 7/22
r = 210 cm
So the radius of the ring = 210 cm = 21 dm
Perimeter = 3(440) = 1320 cm
