A rhombus shaped field has green grass for 18 cows to graze. If each side of the rhombus is 30 m and its longer diagonal is 48 m, how much area of grass field will each cow be getting?

Answer :

 Diagonals divide the rhombus ABCD into two congruent triangles of equal area.


Semi perimeter of = 54 m


Using Heron’s formula,


Area of =



=


= 432 m2


Area of field = 2 x area of



= 864 m2


Thus,


Area of grass field which each cow will be getting = = 48 m2
