Using grid paper is a really helpful way to find the perimeter of shapes, especially those tricky ones with uneven sides. Here’s how I do it:
Draw the Shape: First, I carefully draw the shape on the grid paper. I make sure that each corner matches up with the grid lines. This keeps everything neat and organized.
Count the Sides: Next, I walk around the shape and count how long each side is. Each square on the grid usually counts as one unit. For example, if a side covers two squares, that means it’s 2 units long.
Add it Up: Finally, I just add up all the lengths I counted. If I have a shape with sides that are 3, 2, and 4 units long, then the perimeter (P) is (P = 3 + 2 + 4 = 9) units.
Using grid paper makes it a lot easier to see and calculate the distances clearly!
