Polygon lying in the base of the prism may be a right, that is so, all sides equal, and wrong. If the base of the prism lies in a regular polygon, compute its area by the formula S=1/2P*r, where S is the area of a polygon P is the polygon perimeter (sum of lengths of all its sides), and r is the radius of the circle inscribed in the polygon. Perimeter is the distance around the outside of a shape. Area measures the space inside a shape. Learn how to calculate perimeter and area for various shapes. Area is the quantity that expresses the extent of a two-dimensional figure or shape or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object.Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a.

Example: Sam cuts grass at $0.10 per square meter How much does Sam earn cutting this area: Let's break the area into two parts: Part A is a square: How to find the area of a rhombus The diamond for the first time introduced the ancient Greek mathematics Heron of Alexandria and Poppa. A rhombus has 4 corners and 4 sides, but not immediately possible to imagine its appearance. Learn more at Area of Plane Shapes. Area by Counting Squares. We can also put the shape on a grid and count the number of squares: The rectangle has an area of 15. Example: When each square is 1 meter on a side, then the area is 15 m 2 (15 square meters).
