The perimeter of a circular field is 242 m. The area of the field is
Let the radius if circular field be r
Perimeter of circular field = 2πr
Perimeter of circular field = 242 m
⇒ 2πr = 242 m
⇒ 2 × 22/7 × r = 242 m
⇒ r = 242 × 1/2 × 7/22 = 38.5 m
∴ Radius of circular field = 38.5 m
Area of the field = πr2
= 22/7 × 38.52 m2
= 22/7 × 1482.5 m2 = 4658.5 m2
∴ Area of the field = 4658.5 m2
