Question

There is a quadrilateral field ABCD in which AB=3m,BC=4m,CD=6m,DA=5m and diagonal AC= 5m. The green grass of this field is available for grazing. Find out how many cows can graze the whole field in a day, if one cow can graze one m2 per day.

Answer 1

Answer:

(h)2 =(p)2+(b)2

(5)2= (3)2+(b)2

25 =9+(b)2

25-9 =(b)2

16=(b)2

(4)2 =(b)2

4= b

cow graze in one days in 1 per days=4

cow graze in two days in 2 per days =4*2

cow graze = 8 per days
