The length of a s

length of side of a square field (a) = 20 m

length of the rope (r₁) = 6 m

since it is square the center angle (θ) = 90^o

area of the gazing field =

=

= 28.26 m²

If the length of rope is increased by 2m

The radius of the gazing field (r₂) = 6m + 2m = 8m

area of the gazing field =

=

= 50.24 m²

increase in gazing field = 50.24 – 28.26

= 27.98 m²
