Consider a square shaped farm with sides 56 m each. Four sheep are tethered at four corners of this farm such that they can just reach one another. Calculate the area that is left ungrazed by the sheep.

• 672 sq. m
  
  The area that is left ungrazed= Area of square - 4*(quarter area of circle with r=56/2 or 28 m)
  = 56^2 - 4*(Pi*28^2)/4 = 3136 - 2464 = 672 sq. m.

• area of farm=56*56=3136m2
  area covered by 4 sheep= 3.14*28*28=2464m2
  area left ungrazed = 3136 - 2464=672m2
