Area is the quantity that expresses the extent of a two-dimensional figure or shape , or planar lamina , in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. [1] It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).

The area of a shape can be measured by comparing the shape to squares of a fixed size. [2] In the International System of Units (SI), the standard unit of area is the square metre (written as m 2 ), which is the area of a square whose sides are one metre long. [3] A shape with an area of three square metres would have the same area as three such squares. In mathematics , the unit square is defined to have area one, and the area of any other shape or surface is a dimensionless real number.

From trevor neale of TF Warren Group on May 8, 2017:

May 1 - May 5, 2017
Is it practical to use black light to check for dirt or other foreign matter during surface preparation inspection?

save after for extra help 4n+6-2n=2(n+3) simplify formerly than you clean up first simplify to 2n+6=2(n+3) on the grounds which you re taking 2n faraway from the common 4n. Then distribute on the different area using certainty there is not any sign between the two and the parentheses you multiply yet for the clarification that there are parentheses you multiply 2 by applying way of n and 2 by applying way of three so now your equation is 2n+6=2n+6 as a effect n=a million which additionally recommend it has limitless recommendations on the grounds that of the identity belongings. wish this helped(:
