Perimeter
A perimeter is the total length of the boundary of a shape. It is the sum of the lengths of all the sides of the shape.
Measuring Perimeter:
Formula: P = 2(length of one side)
Example: The perimeter of a rectangle with a length of 5 cm and a width of 3 cm is 10 cm.
Perimeter and Shape Properties:
The perimeter of a circle is always pi (π) times the diameter.
The perimeter of a triangle is equal to the sum of the lengths of its three sides.
The perimeter of a rectangle is equal to 2(length + width).
The perimeter of a square is equal to 4 times the side length.
The perimeter of a hexagon is equal to 6 times the side length.
Real-World Applications of Perimeter:
Perimeter is used in various applications such as:
Calculating the distance around a park or a playground.
Calculating the length of a roll of carpet needed for a room.
Calculating the distance around a building.
Finding the area of a circular table or a rectangular sheet of paper
