This chapter deals with "Area". This includes measuring the land, dividing it into appropriated parts and recasting boundaries of the fields for the sake of convenience. Some of these fields resemble the basic shapes such as square, rectangle trapezium, parallelograms etc., and some are in irregular shapes. For these basic shapes, we work out rules that would give the areas using a few lengths and measurements. We would study some of these in this chapter. We will learn how to calculate areas of triangles, squares, rectangles and quadrilaterals by using some formulae. We will also explore the basis of those formulae. We will discuss how are they derived ? What do we mean by ‘area’?. It includes some area related exercises, examples with solution.
