Answer 2

Answer:

Let ABCD is a rhombus and length of each side is 30

Length of diagonal AC is 48

From Δ ABC,

Let AB =a =30

AC = b =48

BC = c = 30

Now s = (a+b+c)/2

=> s = (30+48+30)/2

=> s = 108/2

=> s = 54 m

Now area of Δ ABC = √{s*(s-a)*(s-b)*(s-c)}

= √{54*(54-30)*(54-48)*(54-30)}

= √{54*24*6*24}

= √{9*6*24*6*24}

= 3*6*24

= 432 m2

Area of rhombus ABCD = 2* area of Δ ABC (since area of Δ ABC = area of Δ ACD)

= 2* 432

= 864 m2

Now area of grash for 18 cows = 864 m2

So area of grash for 1 cows = 864/18 m2 = 48 m2
