### Area of Basic Shapes

#### Area of a Square or Rectangle:

Formula: Area = Length x Width
Example:
Length = 20'
Width = 10'
Area = 10 x 20
Area = 200 sq. ft.

#### Area of a Right Triangle

Formula: Area = 1/2 (base x height)
Example:
Base= 10'
Height = 10"
Area= 1/2 x (10 x 10)
Area = 50 sq. ft.

#### Area of a Circle:

Formula: Area = π r² (pi x radius squared)
Example:
π= 3.141
r = 10'

Area= 3.141 x 10 x 10
Area = 314.1 sq. ft.

### Area of an Irregular Shape

#### Area

Section the irregular area into basic shapes. Calculate the area of each basic shape and add the areas for each together.
Example:
Rectangle: 50' by 40'
Area = 50 x 40 = 2,000 sq.ft.
