Well I don't claim to understand either of these formulas very much but I have combined both of these posts in to a single file. The first method uses the vertical sides being equal where the second none of the sides are equal at all. I invite you guys to check out my handy work, but I didn't change any of the mathematical information.

First method works best if it is a right triangle, one angle is a 90 degree angle. Area equals base times the height divided by two. A triangle with a base of 3 inches, height of 4 inches would be A=(3*4)/2 A=12/2 A=6 The area would be 6 square inches. The second method works better if you do not know the height, or do not feel like figuring the height. First figure up the perimeter of the triangle. This example we will use a triangle with side A 15 inches, side B 10 inches, and side C 7 inches. Perimeter equals A plus B plus C P=15+10+7 P=32 Now for the area Area equals the square route of the perimeter divided by 2 times the perimeter divided by 2 minus side A times the perimeter divided by 2 minus side B times the perimeter divided by 2 minus side c A=sqt((32/2)((32/2)-15)((32/2)-10)((32/2)-7)) A=sqt(16(16-15)(16-10)(16-7)) A=sqt(16*1*6*9) A=sqt(864) A=29.39 square inches.

I'd like to put it up on the web, unfortunately never having trigonometry none of it made any sense to me enough to code in an HTML file at least. Also please use an example to explain the formula.
