A horse is tied to a post by a rope, 8m long at one corner of a rectangular field. What area of the field can the horse graze?
solution pls... tnx...

Draw yourself a picture. The horse can cover a circular area of pi*R^2. But at the corner of a rectangular field (with width longer than the rope), only onequarter of the circle will be in the field.

The rope of horse =14m long
Therefore, radius of circle=14m
Area of quadrant=1/4¡Á¦Ðrsquare =154m square
