area = x/360*pi*r^2
here x =angle of the rectangle corner=90
grazing area = sector area
whose radius =r=21 m
now required area =90/360*22/7*21*21
after cancellation
=693/2m^2

The area which the horse can graze , The area of a quadrant of a circle of radius r = 21 cm
Required area = 1/4 πr²
Required area
= { 1/4 × 22/7 ×( 21 )² } cm²
= 693/2 cm²
= 346.5 cm²
