Mensuration is an extremely important Chapter for Class seven students. It is prescribed by the CBSE and has to be studied in depth in order to gain knowledge about how to calculate the area and Perimeter of various solids and figures. This Chapter deals with the area and Perimeter of various figures such as a Triangle, a Rectangle, circle and the calculation of area of pathways or borders and Rectangle shapes. The Mensuration Chapter of higher Classes mainly deals with problems related to Perimeter and area of other play in closed figures like quadrilaterals, and also deals in-depth about the surface area and volume of solids such as cube, cuboid, and cylinder. Mensuration is the 20th Chapter of RS Aggarwal’s book. In this book, there are detailed tables explaining the Perimeter and area of various figures like equilateral Triangle Isosceles right Triangle Parallelogram rhombus trapezium circle semicircle ring sector of a circle. All these figures and much more is explained in depth in RS Aggarwal’s book. This book is based on the CBSE curriculum so it is advised for the students to practice numerical questions from RS Aggarwal. RS Aggarwal contains eight exercises for Mensuration in the last one being a test paper that will help students to check their progress and to check if their concepts have been cleared.

Why Study This Chapter From R S Aggarwal?

RS Aggarwal has simplified this Chapter for students who may find it a little difficult to study. The test papers prepared by RS Aggarwal are made for the students to keep their progress in check. This Chapter of RS Aggarwal deals with Squares and Rectangles, Triangles as parts of Rectangles, generalizing for other congruent parts of Rectangles, area of a Parallelogram, Area of a Triangle, it deals in-depth about circles, the circumference of a circle, area of a circle, conversion of units, applications, which mainly deals with calculating the pathways or borders. It explains all the formulas in-depth. RS Aggarwal is based on the CBSE curriculum and therefore it is advised for students to prepare for their examinations from this book. RS Aggarwal is known for simplifying hard-to-understand topics and therefore, students who find it difficult to solve some Mathematical equations can now solve them easily as all the solutions provided in RS Aggarwal have reasoning as to what all steps lead to reach a certain solution.

To calculate the area of a figure using a Square d paper, the following conventions are adopted :

Ignore portions of the area that are less than half a Square .
If more than half a Square is in a region. Count it as one Square .
If exactly half the Square is counted, take its area as ½ sq units.
