When finding the perimeter of a figure on a grid,whydo you not count the spaces inside tha grid?

The perimeter is the distance around an object.

A fence enclosing a backyard marks the perimeter of your backyard.

When finding the perimeter of a figure on a grid, you do not count the spaces inside the grid because the perimeter represents the total length of the outer boundary of the figure. It is the sum of all the sides of the figure, which form a closed path along the boundary.

The spaces inside the grid are not part of the outer boundary and do not contribute to the length of the perimeter. Including the interior spaces would result in an inaccurate measurement of the figure's perimeter.

To find the perimeter of a figure on a grid, you usually count only the segments that are on the outer edges of the figure. For example, if you have a square on a grid, you would count only the four sides of the square. You would not count the inner lines that divide the square into smaller squares. By considering only the outer edges, you get an accurate measurement of the figure's perimeter.
