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.
Circle: radius = 41 '
Area = 3.14 x 41 x 41 = 5,278 sq.ft.
Triangle A = 20' by 20'
Area = 1/2 x (39 x 5) = 200 sq.ft.
Triangle B = 10' by 39'
Area = 1/2 x (39 x 5) = 97.5 sq.ft.
Total Area = 7,575.5 sq.ft.
