Area is defined as the total space taken up by a flat 2D shape of an object. Learn the definition, forumulas, area of composite figures, solved examples and more!
Simple formulas calculate the area and perimeter of 2D shapes like triangles and rectangles. Knowing measurements like radius or height helps apply formulas for both 2D and 3D shapes. In math (especiallygeometry) and science, you will often need to calculate the surface area, volume, or perimeter...
The lateral surface is the area of all the sides of the object, excluding the area of its base and top. This division is used for shapes which have an obvious distinction between base and the other part – e.g., for a cylinder, cone, a pyramid or a triangular prism. It’s rarely ...
Some examples of rectangular shapes are the flat surfaces of laptop monitors, blackboards, painting canvas, etc. We can use the formula of the area of a rectangle to find the space occupied by these objects. For example, let us consider a rectangle of length 4 inches and width 3 inches. ...

Volume Formulas for Geometric Shapes. Volume of cube, prism, rectangular prism, pyramid, tetrahedron, cylinder, cone, sphere.
Therefore, these are the only convex polygon among the given shapes. Therefore, a), d) and f) are convex polygons. Example 3: Find the area of a regular convex polygon whose vertices are (6,8), (4.1), and (-3, 6). Solution: Area of a regular polygon is given by the formula,...
While calculus may be needed to find the perimeter of irregular shapes, geometry is sufficient for most regular shapes. The exception is the ellipse, but its perimeter may be approximated. Area is a measure of the space enclosed within a shape. ...
