A horse is tethered to a peg with a 28 metre long repeat
the corner of a 45 metre long and 25 metre wide rectangular grassfield. What area of field does the horse graze?Solution
As the horse is pegged at the corner of the rectangular field, it will graze the area of the field enclosed between the sides of the rectangle and the arc. Area of the field = 1/4 π r2 = 1/4 × 22/7× 28 × 28 = 616 m²
