Chapter Overview
This chapter introduces Heron’s Formula, a method to calculate the area of a triangle when the lengths of all three sides are known. It also extends the application to finding areas of quadrilaterals that can be divided into triangles. The chapter highlights the usefulness of the formula in real-life contexts and geometrical problems where height is not provided.
