In a garden, there are 10 rows and 12 columns of mango trees. The distance between two trees is 2 meters and a distance of one meter is left from all sides of the boundary of the garden. What is the length of the garden ? Correct Answer 24 m

Hints: length বের করতে হবে সর্ব্বোচ্চটির থেকে। ১২ টি column থেকে প্রাথমটির আমরা double করবনা। 11 × 2 = 22, সাথে প্রতি দুই দিক থেকে 1 মিটার যোগ 22 + 2 = 24
