4. Triangles

Formula: Area = 0.5 x B x H

Example: A= 90 feet x 50 feet = 4,500 square feet

Example: Area A = 0.5 x 25 ft. x 35 ft. = 312.5 sq. ft x2 (triangles) =625 sq.ft.

Yard area "D" is 60 ft. x 40 ft. = 2,400 sq. ft. Subtract the 2 triangles (625 sq. ft.).
D=2,400 sq. ft. - 625 sq. ft = 1,775 sq. feet.

Sod Needed = A+B+C (1,300 sq. ft.) + D (1,775 sq. ft) = 3,075 sq. ft.
