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.
You can use the Acre Calculator to find the square footage in a property that has uneven lengths or widths. For example, a parcel that is 70 feet wide but has a length of 160 feet on one side and 140 feet on the other is calculated in two steps. The first thing to do is subtract 20 feet from the longer side so the parcel then forms the shape of a rectangle. Enter 70 in the land width (in feet) space.
