Math problem in the third grade of primary school: plant trees on both sides of a 200-meter-long road, and plant one every 5 meters. If you plant one tree at the beginning and one at the end, how many trees will you plant? Since one plant is planted every 5 meters, 200/5=40 (plants).

But because another tree will be planted at the destination, it is 40+ 1=4 1 (a tree).

Because on both sides, 4 1*2=82 (tree)

My answer is ok! ! ! ! ! ! ! ! ! ! ! !
