Area of a quadrilateral is the space inside the boundary of a quadrilateral. x. length of the diagonal. With this article on the Area of a Quadrilateral, you will learn how to obtain the area of any type of quadrilateral, whether it is a square, trapezium or a triangle. Let a = 4 m, then Area of square = 4*4 =16 m2, Let b = 2 m, h= 4 m, then Area of Rectangle = 2 * 4 = 8m2, Let b = 4 m, h= 5 m, then Area of Rectangle = 4 * 5 = 20m2, Let d1 = 16m and d2 = 10m, Area of a Kite = *16*10 = 80m2, Let b = 3 m, h= 6 m, then Area of Rectangle = 3 * 6 = 18m2. A parallelogram is recognized as a square if all sides are equal and the computation of each angle is 90. Where "a" is the side length of a square. Area of a quadrilateral given four sides and the fact that it is a cyclic quadrilateral. Some of the important properties of a quadrilateral that are needed to understand the topic more clearly are listed below: There are majorly five types of quadrilaterals and that is: Some of the basic properties are discussed below, will cover them in detail in the respective articles to come: The properties of rectangles are as follows: With the complete information on the area, its formula, how to calculate let us check out some solved examples: Solved Example 1: Locate the area of a rhombus whose diagonals are 10 cm and 8 cm respectively.
