Area of a Square
or Rectangle
Area = Length x Width
Example:
Area = 20' x 60'
Area = 1,200 square feet

Area of a Circle
Area= n x R2
n = 3.14
Example:
Area = 3.14 x 20' x 20'
Area = 1,250 square feet


Area of unusual shapes
Calculations can be made by totaling different sections. In this case, calculate and add together the area of the triangle and the rectangle, and one half the area of the circle.


Area of a Triangle
Area = 0.5 x B x H
B = Base        H = Height
Example:
Area = 0.5 x 50' x 100'
Area = 2,600 square feet
