   Let there be x rows and y columns

   since, the number of trees in a row is greater than the columns by 10.

   Thus,

   y – x = 10 or x = y –10

   [tex]y \times x = 200 \\ y(y – 10) = 200[/tex]

   [tex]y = 10± \sqrt{ \frac{100 + 800}{2} } [/tex]

   [tex]y = \frac{10±30}{2} \\ [/tex]

   y = 20,–10

   Neglect the negative value, no of rows = 20
