Area to be fertilized Area to be fertilized

• Basic geometry– L x W = Area

Area to be fertilized
To find your areaTo find your area
• Difficult areas– Divide and conquer– (Length/#of
sections) x sum of Widths = Area
1 2 3
706 sq. ft. 1200 sq. ft. 900 sq. ft.
Length = 140 ft.
Width 1 = 70 ft., 2 = 75 ft., 3 = 55 ft.
Length = 140 = 35 feet
# sections 4
70’ + 75’ + 55’ = 200 ft.
200 ft x 35 ft = 7000 sq.ft.
