Step-by-step explanation:

Side of square=15m

Length of rope=5m=radius

The area available for horse to graze is nothing but "Area of Quadrant of a circle'

∴ Area of Quadrant =

4

π×r

2

=

4

3.14×5×5

=19.625m

2

If the length of rope is increased to 10m then the new radius ,=10m

∴ Area of new quadrant =

4

3.14×10×10

=78.5m

2

∴ Increase in grazing area =78.5−19.625=58.875m
