A horse is tied with a rope in the centre of a square field of side 30m .If the length of the rope is 14m ,find the area of the feild where horse cannot graze

area where horse can't graze = area of square - area it can graze

area of square = 30*30m = 900 m2

area horse can graze = 22/ 7 * 14 * 14 = 616 m²

area hrse cannot graze = 900 - 616 m² = 284 m²
