From the figure, it can be observed that the horse can graze a sector of 90° in a circle of 5 m radius.
Area that can be grazed by horse = Area of sector OACB

Answer:
Step-by-step explanation:
let ABC be the square field
length of rope = 5m
hence r= 5m
area of sector = ○/360°×3.14×5×5
=90°/360°×3.14×25
= 1/4×3.14×25
=1×3.14×25/4
=19.625
