@apoorvk please help out

Answer 3

Aha, are you preparing for CAT?

Answer 4

no ... i am in 7th standard

Answer 5

so there are 9 gaps of 2m each between the 10 rows.
so total length including just the trees --> 9*2 = 18m

plus, 1 m boundary on each side = 2m

so, total length = 18 + 2 = 20m


P.S. - It's not clear what the length actually means - the dimension along the columns or that along the rows. - so check that out.

Answer 6

The answer is 24m right?

Answer 7

No bro ans. is 24m @FoolForMath is right pls can you explain

Answer 8

\[11\times 2+2 =24 \]

Answer 9

I think apporvk found the breadth.

Answer 10

How did you get 11?@FoolForMath

Answer 11

12 columns means 11 gaps.

Answer 12

You need to find width, so dont focus on rows. There are 10 columns, means 10 trees ( one tree in each column). The distance between two trees is 2 meters. It means from first tree to last tree the total distance is 20 meter ( 10*2) and the left out distance of one meter from both the sides ( 2 meters). Therefore the total distance is 20 + 2 = 22 meters.
