Area of Plane Figures and Surface Area from "summary" of NCERT Class 10 Mathematics Solutions by JagranJosh
Area of plane figures refers to the measurement of the region covered by a two-dimensional shape. It is expressed in square units and helps us determine how much space is enclosed within the boundaries of the shape. The concept of area is essential in various fields such as construction, architecture, geometry, and more. By calculating the area of a shape, we can understand its size and make informed decisions based on the available space. Surface area, on the other hand, pertains to the total area occupied by the surface of a three-dimensional object. It includes the area of all the faces or surfaces of the object. Surface area is crucial in real-life scenarios like packaging materials, painting walls, designing objects, and so on. Understanding the surface area of an object helps us estimate the amount of material required for covering or painting it, leading to cost-effective solutions. Calculating the area of plane figures involves applying specific formulas based on the shape of the figure. For example, the area of a rectangle is determined by multiplying its length and wid...
