But this has been exacerbated by human activities which have led to: 1) an increase in greenhouse gas emissions that causes heat to remain trapped within the troposphere, and 2) a decrease in ozone in the stratosphere, causing less sunlight to be absorbed by the ozone layer, resulting in a cooling of the stratosphere.
When measuring for floor tile the rule is: Length x Width + Waste = Amount Needed. Waste Factor will vary based upon tile size, layout, configuration of room, patterns, etc. Typical waste factor is about 10%. Add 15% for tile being installed diagonally or for a room with lots of jogs and corners.
Multiply the two measurements together. Multiplying the length and width together is all you need to do to find the square footage of this section. Example: For a rectangular section with a length of 12 feet and a width of 10 feet: A = L * W = 12 * 10 = 120 sq ft.
