### How To Measure

#### Square or Rectangle

Measure the Length & Width and multiply.  Length x Width = Area
(12’ x 24’ = 288 ft2)

#### Right Triangle

Multiply the two sides that contact the right angle and divide by two.  Length x Width / 2 = Area
(12’ x 24’ = 288 ÷ 2 = 144 ft2)

#### Circular

Multiply the radius with the radius then multiply by 3.14. Radius is a straight line from the center of a circle to the outside of the circle. ##### Full Circle: (6’ x 6’ = 36 x 3.14 = 113 ft2) ##### Half Circle: Divide full circle radius by 2
(6’ x 6’ = 36 x 3.14 = 113 / 2 = 56.5 ft2) ##### Quarter Circle: Divide full circle radius by 4
(6’ x 6’ = 36 x 3.14 = 113 / 4 = 28.25 ft2)
