### Discussion :: Arithmetic Reasoning - Section 1 (Q.No.13)

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

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.

 Rakesh said: (Sep 20, 2011) 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.

 Imran Ali said: (Sep 17, 2014) 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.

 Sandy said: (Sep 4, 2018) Why don't you take 10 in a row?
