**A horse is placed for grazing inside a rectangular field 70 m by 52 m and is tethered to one**

**corner by a rope 21 m long. On how much area can it graze ?**

**Solution:** The part of the field on which the horse can graze = Area of the quadrant of the circle with radius 21 m long

= 1 /4 x Π r^{2} = 1 /4 x 22 / 7 x 21^{2} m^{2}

= 693 / 2 m^{2} = 346.5 m^{2}.
