Area of square field =12100sqmetres
∴ Side of field= 12100=110 metres
∴ Its perimeter =4xside
=4x110=440 metres
Sience perimeter of square field = perimeter of circular field
∴ Perimeter of circular field =440 metres
Let the radius of field be r metres
∴ 2π=440
r=44440×7
=70 metres
∴ Area of circular field=πr2
=722×70×70=15400m2
