Area of a triangle is the region enclosed by it, in a two-dimensional plane. As we know, a triangle is a closed shape that has three sides and three vertices. Thus, the area of a triangle is the total space occupied within the three sides of a triangle . The general formula to find the area of the triangle is given by half of the product of its base and height. Area of a triangleLet us ...
