13. 

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

[A]. 20 m
[B]. 22 m
[C]. 24 m
[D]. 26 m

Answer: Option C

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.

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.

Ved Prakash said: (Feb 7, 2012)  
I also think answer should be 26.

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

Chaman said: (Apr 12, 2012)  
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.

Imran said: (May 29, 2012)  
Yes, the answer is 24 only. He asked only the length of the garden, but not breadth.

Subbarao said: (Dec 4, 2012)  
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.

Cyrus said: (Feb 28, 2013)  
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.

In Q if height is asked then how it should be solve, please someone tell me?

Harsh Pamnani said: (Oct 5, 2014)  
Answer can be 20m also.

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

Imran Ali said: (Oct 17, 2014)  
How we calculate height in the same Q some one tell me?

Udaya said: (Jan 17, 2015)  
We can't calculate the height because here it is given only no.of tree.

Kunal said: (Jul 10, 2015)  
What is the height of a 1900 metre mango tree?

Lizzy said: (Nov 1, 2015)  
Why are there 12 plants in each row, if there are 10 plants in a row in the question?

Please explain?

Costas said: (Dec 23, 2015)  
It is not determined which side's length must be calculated. The question could instead ask for the area without any further information.

Siyad said: (Jun 13, 2017)  
@Costas.

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

Abix said: (Mar 13, 2018)  
It is 22 since only row can be considered as length so 2*10=20.

Then 20+1+1=22.

Shreyash said: (Aug 13, 2018)  
@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.

Why don't you take 10 in a row?
