The length of the side of a square-shaped plot is 10 meters. How many trees at a distance of 2 meters

The length of the side of a square-shaped plot is 10 meters. How many trees at a distance of 2 meters from each other can be planted along the perimeter of the plot.

1) Find the length of the plot perimeter. Since the section is square, all its sides will be the same length, and the perimeter will be
10 * 4 = 40 cm.
2) Let’s calculate how many trees can be planted on one side of the site:
10: 2 = 5 pcs.
3) Since the length of the side of the site fits an integer number of trees without a remainder, in each corner of the square there will be a tree. A square has 4 corners, which means that 4 trees will belong to two sides at the same time, so the number of trees will be equal to:
40: 2 – 4 = 20 – 4 = 16 pcs.
