How many trees can be planted at a distance of 6 metres each around a rectangular plot whose length is 120 m and breadth is 90 m?

Open in App

Solution

Length of the rectangular plot = 120 m

Breadth = 90 m

$∴$ Perimeter of the rectangular plot = 2 [length + breadth]

= 2 [120 m + 90 m]

= 2 $\times$ 210 m

= 420 m

Now distance between two trees = 6 m

Number of trees around the rectangular plot $= \frac{420}{60} = 70$
