**How to calculate the area of a triangle ABC when given**

Some oil is filled in a right circular cylendrical vessel. The rafius of the base of the vessel is 6 cm. Some iron balls each of diameter 3 cm are com... 29/05/2011Â Â· Thus when we calculate the vector product of R and S, the length of the normal vector equals the area of the parallelogram formed by those vectors. The triangle forms half of the parallelogram and therefore half of the area.

**Finding Parallelogram Vertices EDC**

Pick one vertex, let say V1, as "origin" Get the two vectors of from this point to the other two points (V2-V1) and (V3-V1) Calculate the cross product between these two vectors...Find the area of the dodecagon. first, what is the area of a dodecagon and second how to find it with just the distance between two oppositve vertices. i found that a dodecagon can be asked by Knights on December 18, 2012

- This lets one take the cross-product of 2D vectors, and use it to compute area. Given a triangle with vertices for i = 0,1,2, we can compute that: And the absolute value of the third z-component is twice the absolute area of the triangle. However, it is useful to not take the absolute value here, and instead let the area be a signed quantity. This formula for area is a very efficient
- One way to do it would be to first find out the length of each of the 3 sides, by simply applying Pythagorus. e.g. AB = $\sqrt{(2-0)^2 + (1-1)^2 + (4-3)^2}=\sqrt5$ You can do this for all of the sides, and it is possible to find the area of a triangle given the length of each of its sides.
- We therefore find the point of intersection, T, of the medians of a triangle by finding a kind of average of the position vectors of the vertices. This rule is therefore an extension of the Midpoint Rule.
