## Perimeter and Area

 6.3 Perimeter and Area

We will learn to determine the perimeter of a polygon shape with up to eight sides.

 PERIMETER The perimeter is the sum of the lengths of all the sides of a closed two-sided figure where the ends of two or more lines meet the other ends. The standard symbol for perimeter in mathematics is the letter P.

Perimeter of a Square / Cube
EXAMPLE:

$$\text{P}=a+a+a+a=4a$$

Perimeter of a Rectangle
EXAMPLE:

$$\text{P}=a+b+a+b=2a+2b$$

Perimeter of an Equilateral Triangle
EXAMPLE:

An equilateral triangle has 3 equal sides.

$$\text{P}=a+a+a=3a$$
