Answer:
The density the chicks per unit area = 5/6
Explanation:
It is given that, a rectangular farm 15 m wide and 20 m long has 250 chicks in it.
To find the area of farm
Area = Length * Breadth
= 20 * 15
= 300 square meter
To find the density
Here number of chicks = 250
Density = Number of chicks/Area
= 250/300
= 5/6
