How do you work out the area of an object?

Can't answer, it depends entirely upon the object, and whether it is an object in 3 dimensions (in which case it has a volume rather than an area) or 2 dimensions (eg on a flat plane, like a piece of paper).How do you work out the area of an object?
Fill a bucket up with water to the brim. Now place your object in the bucket full of water. Any over-spill from the bucket = the volume of your object.





Eureka!How do you work out the area of an object?
HEIGHT X WIDTH = AREA
Much easier to use Autocad or similar if it is an obscure shape ... but for square/rectangle it is length by width ...if it is circle it is pi (3.145)rsquared(radius by radius)... if it is triangle it is half the base by the perpendicular height ... hope that helps
For a triangle you can use 1/2 base x height or 1/2 b c Sin A
Some variation on length times width, depending on the shape of the object.





Ask a vague question, get a vague answer. Sorry.
height x width x depth
Well, if it's not something simple like a rectangle or circle, I draw it (or at least a reasonable approximation) in a CAD program and let the software work it out, but you could use integral calculus if you wanted.
area = length x width





provided that length and width are perpendicular to each other
You split it into triangles and work out the area of each one.
