Exercise 9.1 class 8 solution-what is Mensuration ?
Mensuration is a branch of mathematics that deals with the measurement of geometric objects such as length, area, volume, and other quantitative attributes of shapes and figures. It’s a fundamental part of geometry that helps us calculate and understand the size, dimensions, and properties of various geometric objects and solids. Here are some key concepts in mensuration:
- Length: In mensuration, the length of an object refers to the measurement of one dimension. For example, the length of a line segment or a rectangle’s sides.
- Area: Area deals with the measurement of the surface covered by a geometric figure. Common shapes with area calculations include rectangles, triangles, circles, and polygons.
- Volume: Volume pertains to the space occupied by a three-dimensional object. Examples of objects with volume calculations are cubes, spheres, cylinders, and cones.
- Perimeter: Perimeter is the measurement of the total distance around the boundary of a two-dimensional figure. Common shapes with perimeter calculations include squares, rectangles, and triangles.
- Surface Area: Surface area involves calculating the total area of the exterior surfaces of a three-dimensional object. It’s often used with shapes like cubes, rectangular prisms, and cylinders.
- Density: Density is the mass per unit volume of an object and is commonly used in physics and engineering.
- Circumference: Circumference is specifically the measurement around the boundary of a circle. It’s relevant to understanding the properties of circles.
- Similarity: Mensuration can also involve determining the similarity or congruence of geometric objects.
By applying mensuration concepts, one can solve practical problems related to dimensions, quantities, and physical attributes of various geometric shapes and structures.
Exercise 9.1 class 8 solution-Geometrical shapes and their associated formulas
Geometrical shapes, also known as geometric shapes, are fundamental figures in geometry that are defined by their characteristics, such as the number of sides, angles, and dimensions. Here are some common geometrical shapes and their associated formulas.
Here is a table of common geometrical shapes along with their corresponding formulas for perimeter (P), area (A), and volume (V) where applicable:
Please note that not all shapes have volume formulas, as volume is primarily applicable to three-dimensional shapes. Also, the variables used in the formulas represent specific dimensions or measurements of the shapes (e.g., rr for radius, hh for height, etc.).
Example 9.1.1- The length and breadth of a rectangular field are in 3:2 .if the area of the field is 294 meter per square .find the cost of fencing the field at rs.8 per meter.
