• 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.

• 10 rows 20 column
  Distance b/w each tree = 2 meter
  Rows gives us length n column gives us breadth
  Note if n elements are there then total no. of gaps b/w them = n-1
  Thus the breadth = 2*(20-1)=38m
  length = 2*(10-1)=18m
  Now additional border of 1m
  Thus breadth = 1+38+1=40m
  And length =1+18+1=20m
