The area of a two-dimensional shape is found by counting the number of squares that cover the shape. Many formulas have been developed to quickly find the area of standard polygons, like triangles and parallelograms. This page titled 7.2.2:.. Area is a quantity that expresses the extent of a two-dimensional figure or shape or planar lamina in the plane. Lamina shapes include 2D figures that can be drawn on a plane, e.g., circle, square, triangle, rectangle, trapezium, rhombus and parallelogram. A polygon is a two-dimensional shape that is formed by straight lines.

#visuallearningportalMath is so much fun. As we have learnt about area in our last video. LINK- https://youtu.be/lMklyTpMj9UNow in this video you can learn h.. Area formula. The area of a two dimensional shape or geometric figure is the space contained within its perimeter. Area formulas of common shapes. The exact area of many common shapes can be calculated using well-defined formulas. Circle. The area of a circle with radius r is: A = πr 2. Triangle. The area of a triangle with base, b, and height.
