Mensuration is the skill of measuring the length of lines, areas of surfaces, and volumes of solids from simple data of lines and angles. Mensuration, in its literal meaning, is to measure. Mensuration deals with the size, region and density of different forms, both 2D and 3D. Now, in the introduction to Mensuration, let's think about 2D and 3D forms and the distinction between them. In this chapter, we learn about the concept of area and perimeter of plane figures. These two concepts are of great importance in our daily lives which helps to determine their measurements.
