Area and Volumetric Determination
A Point
No length, no width, no depth..
No Dimensions
A Line
It has one dimension: length
A rectangle, or plane
This geometric figure has two dimensions: length and heigth. It is, therefore, two dimensional.
A rectangle, or plane

The area of virtually any geometric
figure can be determined by breaking
the figure up into triangles.
For instance, take the figure in the middle
If you had a field that looked like this, and needed to know how many acres were in it….
You could break the field up into triangles like this…
