Using
Triangulating to Find Area!
Does triangulating serve us any purpose?
The answer is of course, of course!!! Since we already
know how to find Areas
of Triangles , and we can divide every polygon or shape into triangles,
we can find the area of polygons!
We For this Exercise,
you can assume the length of each side of each polygon is 1 unit!
