Students have learnt that for a closed plane figure, the perimeter is the distance around its boundary and its area is the region covered by it. Students also learnt that the area and perimeter of various plane figures such as triangles, rectangles, circles etc. to find the area of pathways or borders in rectangular shapes. In NCERT Grade 8 Mathematics Chapter 11, Mensuration, an attempt to try to solve problems related to perimeter and area of other plane closed figures like quadrilaterals. Students will also learn about surface area and volume of solids such as cube, cuboid and cylinder.
Introduction to Mensuration, Revision of previous lessons, Area of Trapezium, Area of a General Quadrilateral, Area of special quadrilaterals, Area of a Polygon, Solid Shapes, Surface Area of Cube, Surface Area of Cuboid and Cylinder, Volume of Cube, Volume of Cuboid and Cylinder, Volume and Capacity are some of the basic concepts learnt in this chapter. A relationship between different geometrical shapes is successfully established through the learning of this chapter. The students also learn to apply mathematical formulas while dealing with geometry in this chapter.
