Let ABC be the given triangle. We are to construct a triangle equal in area to this triangle.
Principle followed
The areas of all triangles of same base are same if they are placed in between two parallel sraight lines.
Steps
A straight line PQR parallel to base BC is drawn with the help of a ruler and a compass.
B and C may be joined with any point on the line PQR to get a triangle equal in area of triangle ABC. Here
