A horse is tied with a 21 m long rope to the corner of a field which is in the shape of an equilateral triangle. Find the area of the field over which it can graze.
-----------
If the altitude of the triangle >= 21 m, then
Area = (1/6)*pi*r^2
= 147pi/2 sq meters
------
If the side of the triangle <= 21 m, then
Area = area of the triangle.
------
Between those 2, you'll have to spec the side length of the triangle.
