5.1.7.1 Rectangles

This form is quite popular. Since the area of a rectangle is equal to the product of its length and width, while constructing such  diagram both length and width are considered. When two set of figures are to be represented by rectangles, either of the two methods may be adopted. We may represent the figures as they are given or may convert them to percentage and then subdivide the length into various components. The latter method is more popular than the former as it enables comparison to be made on a percentage basis.
