उत्तर
Here, length of rectangular lawn = 72 m and breadth of rectangular lawn = 18 m
∵ Perimeter of rectangle = 2 × (Length + Breadth)
∴ Perimeter of rectangular lawn = 2(72 + 18) = 2(90) = 180 m
If 3 shrubs can be planted in a metre of hedge.
Then, number of shrubs = 3 × Perimeter of rectangular lawn = 3 × 180 = 540
