To calculate the area of the triangle, build on vectors, one should remember, that the magnitude of the vector product of two vectors equals to the twice of the area of the triangle, build on corresponding vectors:
Therefore, the calculation of the area of the triangle, build on vectors divided into several steps. First of all, on need to find the vector which is the vector product of two initial vectors, then find magnitude of the found vector and divide the resulting value by two.
All these steps can be performed by means of our online step by step calculator.
