Question

Four horses are tethered at the four corners of a square plot of side 63 m so that they just cannot reach one another the area left and gas day is

Answer 1

Answer:

Each horse can reach one quadrant of a circle of radius 31.5 m

Then the total area the horses can reach is

4 * pi * R^2 / 4 = pi * 31.5^2 = 3117 m^2

The area of the square is 63^2 = 3969 m^2

So the area they cannot reach is 3969 - 3117 = 852 m^2
