Question

how many trees can a be planted at a distance of 4 metres each, around a rectangular plot whose length is 300 m and breadth is 200 m ?​

Answer 1

ANSWER : 246 plants

EXPLANATION :

Given:

• Distance between two trees = 4 meter
• Length of plot = 300 meter
• Breadth of plot = 200 meter

⇨On the both length we can plant = $\frac{300}{4}$×2

$\boxed{ = 150 \:plants}$

⇨similarly,

⇨On the both breadth we can plant=$\frac{200}{4}$×2

$\boxed{ = 100 \:plants}$

⇒$\bold\green{Total\:plants}$

⇨100+150

⇨250

___________________________________________

We have to subtract 4 from the sum because we counted the corner trees in both direction.

___________________________________________

∴Total trees that can be planted

⇨250-4

⇨246 plants
