Home How To Measure

**Formula**

Area = L x W

L = length

W = width

**Example**

Area = 90 feet x 50 feet

Area = 4,500 square feet

The following illustration reduces the area to be sodded around the house (A, B, C) and the backyard (D) to rectangles.

**Example**

Area A = 50' x 10' = 500 sq. ft.; Area B = 30' x 10' = 300 sq. ft.; Area C = 50' x 10' = 500 sq. ft.; Area D = 40' x 30' = 1200 sq. ft.

**Sod Needed: A (500 sq. ft.) + B (300 sq. ft.) + C (500sq. ft.) + D (1,200 sq. ft.) = 2,500 sq. ft.**

**Formula**

Area = 0.8 L x W

L = length

W = width at midpoint

**Example**

Area = 0.8 x 60 feet x 40 feet

Area = 1,920 square feet

(within 5% accuracy)

**Formula**

Area = πR^{2}

π = 3.14

R = radius

**Example**

Area = 3.14 x 30 feet x 30 feet

Area = 1,413 square feet

The half circle backyard has a radius of 30 feet. A complete circle would be π 30^{2} or 3.14 x 30 ft. x 30 ft. = 2,826 sq. ft. Half would be 1,413 sq. ft.

**Sod Needed: A + B + C (1,300 sq. ft.) + D (1,413 sq. ft.) = 2,713 sq. ft.**

**Formula**

Measure the length of the longest axis across the area. Every 10 feet along the length, measure the width of the area at right angles to the length line. Total all widths and multiply by 10.

**Example**

Area = 40 feet + 30 feet + 50 feet x 10

Area = 1,200 square feet

**Formula**

Area = 0.5 x B x H

B = base

H = height

**Example**

Area = 0.5 x 25 feet x 25 feet = 312.5 square feet x 2

(triangles) = 625 square feet

Area = 625 square feet

**Formula**

Area = 0.5 x (A + B) x H

A = one parallel side

B = second parallel side

H = height perpendicular to two parallel sides

**Example**

Area = 0.5 x A + B (100 feet) x H (30 feet)

Area = 1,500 square feet

**Sod Needed: A + B + C (1,300 sq. ft.) + D = 2,800 sq. ft.**

**Formula**

Divide area into sections of regular geometric shapes, calculate area of individual sections, then total.

**Example**

Triangle 0.5 x B (15 feet) x H (30 feet) = 225 square feet

Rectangle 30 feet x 45 feet = 1,350 square feet

Circle π (3.14) x 9 x 9 = 258 square feet / 2 = 127 square feet.

**So Needed: 225 sq. ft. + 1,350 sq. ft. + 127 sq. ft. = 1,702 sq. ft.**
