There are only few steps to find the area of the triangle in a simple method. First you consider a triangle, and to find the area in a simple manner just add the triangle of same properties and side lengths as same as the first one and attach to it. Then we know the formula to calculate the area of the square. Then find area of the square by side*side. Then you will get the area of the square, now divide the area by two, as we add another triangle. Then the area of the triangle will be obtained and put a power of 2 to the answer.
