# Q5.    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?

To find the area of the rhombus:

We first join the diagonal AC of quadrilateral ABCD.  (See figure)

Here, the sides of triangle ABC are,

So, the semi-perimeter of the triangle will be:

Therefore, the area of the triangle given by the Heron's formula,

Hence, the area of the quadrilateral will be:

Therefore, the area grazed by each cow will be given by,
