Q10 of 27 Page 228

A horse is placed for grazing inside a rectangular field 70m by 52 m and is tethered to one corner by a rope 21 m long. How much area can it graze?

The length of rope to which horse is tied will be equal to the radius of the quarter circle that the horse grazes.

⇒ Radius, r = 21m


As we know that,





⇒ Area = 346.5 sq.m


∴ The area that horse can graze is 346.5 m2
