Mensuration Important Terminologies
Terms | Unit | Definitions |
Area | Square units | The region enclosed by the 2D figure is called the area. |
Perimeter | Linear units | The length of the boundary of a 2D figure is called the perimeter. |
Volume | Cubic units | The measure of the amount of space that a three-dimensional object occupies, is usually expressed in cubic units. |
Curved Surface Area | Square units | The area of the outer surface of a three-dimensional object that has a curved surface, such as a cylinder or cone. |
Lateral Surface Area | Square units | The area of the outer surface of a three-dimensional object that does not include its top or bottom, such as the sides of a prism or cylinder. |
Total Surface Area | Square units | The sum of the area of all the surfaces of a three-dimensional object, including its base and top. |
Square Unit | Square units | A unit of measurement is used for area, where one unit is equivalent to the area of a square with sides of length 1 unit. |
Cube Unit | Cubic units | A unit of measurement is used for volume, where one unit is equivalent to the volume of a cube with edges of length 1 unit. |
Mensuration 2D Formula & Aptitude Questions
Mensuration 2D is an important topic in Quantitative Aptitude, which mainly deals with problems related to the perimeter and area of two-dimensional shapes such as triangles, squares, rectangles, circles, parallelograms, etc. In Quantitative Aptitude, this topic does not have many variations and most of the questions are based on certain fixed formulas. The ability to quickly and accurately calculate the area and perimeter of 2D shapes is an essential skill required for various competitive exams, including aptitude tests.
It is therefore important for candidates to have a good understanding of 2D mensuration concepts and be able to apply them to solve problems
