It is called a trapezoid in North America and a trapezium in Britain and other countries. c = edge c The opposite sides of a parallelogram are of equal length and the opposites angles are equal. Example: What is the area of this circle? Longer Diagonal. The trick to finding the area of an irregular polygon or complex shape is to break the shape up into regular polygons such as triangles and squares first, then find the area of those shapes and add them together to find the total. The apothem is the side that is represented by x√3. Home / Mathematics / Area; Calculates the area of a triangle given three sides. l2 = inner length 10/20/2016; 15 minutes to read; In this article. So, Using above formula we get, Area = L X B = (14 X 8) = 112 m2 Hence, in this way we can calculate area of land which are in rectangular shape. If the height and width are in cm, the area is shown in cm². The area of a square is equal to the length of one side squared. A = πr2. b Axis: meter. Normally, the longer side is called the length and the shorter side is called the width. It’s essential to measure all lengths in the same unit of measure or convert all lengths to the same unit before calculating area. Due to significant price increases we can no longer offer all functionally. To find the area of an equilateral triangle, we can use the following formula: The area of an equilateral triangle (with all sides congruent) is equal to, where s is the length of any side of the triangle. Area of rectangle = length * breadth. The apothem of a regular polygon is a line segment from the centre of the polygon to the midpoint of one of its sides. If you have an irregular shape, you may need to break it up into smaller shapes with a known formula for the area. A a = 0.7854 d i 2 (6) To calculate the area of a planar object, you’ll need the formula for the object depending on the shape of the object. Show Step-by-step Solutions If 2a and 2b are the lengths of the major and minor axes of the ellipse, then the area of the ellipse is πab.
