Heron’s Formula, Three-Point Coordinate Formula. • Plot each of the following points, and connect them to form the triangle ABC. A(-2,5); B(1, 3); C(-1,0) • Find the area of the triangle using two techniques: Heron's Formula. The three-point coordinate formula (see Math Open Reference, 2009). Show your work in detail. C++ Exercises, Practice and Solution: Write a program in C++ to find the area of any triangle using Heron's Formula.

Heron formula requires you know only the sides of a triangle to compute the area. Note you can use another approach i.e. determine the height of the triangle and use our familiar: A = 1/2 bh but why not use only the sides. Heron formula requires you know only the sides of a triangle to compute the area. Note you can use another approach i.e. determine the height of the triangle and use our familiar: A = 1/2 bh but why not use only the sides. Heron's formula is a formula that can be used to find the area of a triangle, when given its three side lengths. It can be applied to any shape of triangle, as long as we know its three side lengths. The formula is as follows: Although this seems to be a bit tricky (in fact, it is), it might come in handy when we have to find the area of a ...
