How to calculate the area of a square
Example: 25’ x 25’ = 625 sq. ft.
 Measure the length and the width of your area in feet.
 Multiply the two numbers together.
 Total is the square footage required.
Example: 25’ x 25’ = 625 sq. ft.
How to calculate the area of a rectangle
Example: 40 ’ x 15 ’ = 600 sq. ft.
 Measure the length and the width of your area in feet.
 Multiply the two numbers together.
 Total is the square footage required.
Example: 40 ’ x 15 ’ = 600 sq. ft.
How to calculate the area of a circle
Example: 20’ x 20’ = 400 x 3.14 = 1,256 sq. ft.
 To calculate the sq. ft. of a circle, multiply the radius by the radius, then multiply by 3.14.
 The radius is half the distance across the circle.
Example: 20’ x 20’ = 400 x 3.14 = 1,256 sq. ft.
How to calculate the area of a triangle
Example: 10’ x 10’ = 100 ’ ÷ 2 = 50 sq. ft.
 To figure the area of a triangle, multiply the base by the height and divide by 2
Example: 10’ x 10’ = 100 ’ ÷ 2 = 50 sq. ft.
How to calculate the area of a trapezoid
Example: 20’ + 10’ x 15’ ÷ 2 = 225 sq. ft.
A trapezoid is a 4 sided figure with one pair of parallel sides.
To find the area of a trapezoid,
 Measure the length of each parallel side in feet.
 Add the lengths together.
 Multiply the result by the height.
 Divide the result by 2
Example: 20’ + 10’ x 15’ ÷ 2 = 225 sq. ft.
How to calculate the area of a parallelogram
Example: 25’ x 15’ = 375 sq. ft.
 A parallelogram is a 4sided shape formed by two pairs of parallel lines.
 Opposite sides are equal in length and opposite angles are equal in measure.
 To find the area of a parallelogram, multiply the base by the height.
Example: 25’ x 15’ = 375 sq. ft.
How to calculate the area of an odd shaped oval
Example: (40' x 20' = 800 sq. ft.) + (10' x 10' x 3.14 = 314) = 1,114 sq. ft.
 For example, a golf practice tee with bell shaped ends actually looks as if it is an irregular shape. However, it can be easily divided into a number of regular shapes—a rectangle and two half circles.
 Therefore the formulas for the area of a rectangle and area of a circle can be used to calculate the area.
Example: (40' x 20' = 800 sq. ft.) + (10' x 10' x 3.14 = 314) = 1,114 sq. ft.
How to calculate the area of an odd shaped area
Example:
 Any area bounded by more than 4 sides may be divided into a series of triangles by diagonal lines and the area of each computed by multiplying the base times the height, and dividing by 2.
 The sum of the triangles is the total square footage required.
Example:
 (10' x 8’ = 80) + (20’ x 7’ = 140) ÷ 2 = 110 sq. ft.
