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

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

1) Find the length of the perimeter of the site. 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, there will be a tree in each corner of the square. 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.
