In a garden, there are 10 rows and 12 columns of mango trees. The distance between the two trees is 2 metres and a distance of one metre is left from all sides of the boundary of the garden. The length of the garden is
20 m
22 m
24 m
26 m
Answer: Option
Explanation:

Each row contains 12 plants.

There are 11 gapes between the two corner trees (11 x 2) metres and 1 metre on each side is left.

Therefore Length = (22 + 2) m = 24 m.

Distance between boundary and first tree=1 meter.

And there are 12 trees so distance between 12 trees =11*2=22 meters.

(distance between two trees is 2 meters).

Distance between boundary and last tree=1 meter.

1+22+1=24 meters.

If 2m is left on each side than answer shold be 26

There are 11 gapes between the two corner trees (11 x 2) metres and 1 metre on each side is left.

Therefore Length = (22 + 2+2) m = 26 m.

Distance can also be measured considering there are 12 trees in 1 row, each having 1 meter on either side of each tree i.e. 2 meters/tree.

Therefore: 12 trees*2 meters=24 meters length.

Answer would be 24m. Because one meter is left from all sides but its length is asked in question. So 22+ (1m from left+1m from right) =24m.

@Abix.

But number of column is more here, so we have to go column-wise in order to get length.

So, 11 gaps * 2 (distance b/w gaps) = 22.

It is not determined which side's length must be calculated. The question could instead ask for the area without any further information.

Answer can be 20m also.

Because it is not mentioned that which side is length I can consider 20m as a length also.

I also think answer should be 26.

Because one metre is left from all sides of the boundary of the garden.

Why are there 12 plants in each row, if there are 10 plants in a row in the question?

Please explain?

@Costas.

Length means the longest side. So here 10 and 12. So 12 is length and 10 is the breadth.
