Answer» Area of Triangle =Now, we can easily derive this formula using a small diagram shown below.how to find area of triangle using coordinates of THREE vertices of triangleSuppose, we have a triangle ABC as shown in the diagram and we want to find its area.Let the coordinates of vertices are (x1, Y1), (X2, y2) and (x3, y3).We draw perpendiculars AP, BQ and CR to x-axis.Area of = Area of Trapezium ABQP + Area of Trapezium BCRQ - Area of Trapezium ACRP Area of = = Example: Find area of triangle whose vertices are (1, 1), (2, 3) and (4, 5)Solution:We have (x1, y1) = (1, 1), (x2, y2) = (2, 3) and (x3, y3) = (4, 5)Using formula:Area of Triangle = = = ==-1Because, Area cannot be negative. We only consider the numerical value of answer. Therefore, area of triangle = 1 sq units.Step-by-step explanation:
