Answer:
We use a ruler to measure length of the sides of a small regular shape. The perimeter is determined by adding the lengths of the sides/edges of the shape.
For small irregular shapes, we can use a string of thread and place it exactly along the boundary of the shape, once. The total length of the string used along the boundary is the perimeter of the shape.
Step-by-step explanation:
We often find the perimeter when putting up Christmas lights around the house or fencing the backyard garden. Other examples may include finding the total length of the boundary of the soccer field or the length of the crochet or ribbon required to cover the border of a table.
