Finding Polygon AreasDate: 03/20/97 at 20:29:42 From: Nichole Worden Subject: Area of Polygons How the heck do I find the area of polygons? Date: 03/21/97 at 05:09:56 From: Doctor Mitteldorf Subject: Re: Area of Polygons Dear Nichole, It depends on the shape of the polygon. What will always work is to divide the polygon into triangles, and then find the area of each triangle. Have you ever seen the formula for finding the area of a triangle if you know the lengths of the 3 sides: a, b, and c? It's a neat formula, and it's interesting to figure out why it works. The formula is sqrt (s(s-a)(s-b)(s-c)) This is the square root of the product of four terms. s represents the "semiperimeter", or half the sum of a, b and c. -Doctor Mitteldorf, The Math Forum Check out our web site! |
