The perimeter is the distance around an object. It is calculated by adding together all the lengths of an object.
- It is a closed plane shape or figure
- It has straight sides
Some of the polygons are as follows:
To find the perimeter of the polygon, you would just add the length of all sides together.
So, the perimeter of this square is 7 + 7 + 7 + 7= 28 units
Remember: Perimeter of a polygon = sum of the length of all sides
The length and the width of the mat is 8 feet and 6 feet respectively. To find the perimeter, we need to add all the sides.
The perimeter will be:
8 + 6 + 8 + 6 = 28
So, the perimeter of the picnic mat is 28 feet.
The length and the width of the card is 6 inches and 4 inches respectively.
The Perimeter of the card is:
6 + 4 + 4 + 6 = 20
So, 20 inches of yarn is required for the card.
